Criticism
Bart's rebellious, bad boy nature, which underlies his misbehavior and rarely leads to any punishment, led some people to characterize him as a poor role model for children. In schools, educators claimed that Bart was a "threat to learning" because of his "underachiever and proud of it" attitude and negative attitude regarding his education. Others described him as "egotistical, aggressive and mean-spirited". In a 1991 interview, Bill Cosby described Bart as a bad role model for children, calling him "angry, confused, frustrated". In response, Matt Groening said, "That sums up Bart, all right. Most people are in a struggle to be normal [and] he thinks normal is very boring, and does things that others just wished they dare do." On January 27, 1992, then-President George H. W. Bush said, "We are going to keep on trying to strengthen the American family, to make American families a lot more like the Waltons and a lot less like the Simpsons." The writers rushed out a tongue-in-cheek reply in the form of a short segment that aired three days later before a rerun of "Stark Raving Dad" in which Bart replied, "Hey, we're just like the Waltons. We're praying for an end to the Depression, too."
The show also received criticism from the nuclear power industry in its early years, with its portrayal of the evil boss Mr. Burns and "bungling idiot" employees (including Homer Simpson himself) with their lack of safety and security. In a letter to the nuclear power-backed U.S. Council for Energy Awareness, producer Sam Simon apologized, stating, "I apologize that the Simpsons have offended a lot of people in the energy industry. I agree with you that in real life, Homer Simpson would not be employed at a nuclear power plant. On the other hand, he probably wouldn't be employed anywhere."
Various episodes of the show have generated controversy. The Simpsons visit Australia in "Bart vs. Australia" (season six, 1995) and Brazil in "Blame It on Lisa" (season 13, 2002) and both episodes generated controversy and negative reaction in the visited countries. In the latter case, Rio de Janeiro's tourist board—which claimed that the city was portrayed as having rampant street crime, kidnappings, slums, and monkey and rat infestations—went so far as to threaten Fox with legal action. Groening was a fierce and vocal critic of the episode "A Star Is Burns" (season six, 1995), which featured a crossover with The Critic. He felt that it was just an advertisement for The Critic, and that people would incorrectly associate the show with him. When he was unsuccessful in getting the episode pulled, he had his name removed from the credits and went public with his concerns, openly criticizing James L. Brooks and saying the episode "violates the Simpsons' universe". In response, Brooks said, "I am furious with Matt, ... he's allowed his opinion, but airing this publicly in the press is going too far. ... his behavior right now is rotten."
"The Principal and the Pauper" (season nine, 1997) is one of the most controversial episodes of The Simpsons. Many fans and critics reacted negatively to the revelation that Seymour Skinner, a recurring character since the first season, was an impostor. The episode has been criticized by Groening and by Harry Shearer, who provides the voice of Skinner. In a 2001 interview, Shearer recalled that after reading the script, he told the writers, "That's so wrong. You're taking something that an audience has built eight years or nine years of investment in and just tossed it in the trash can for no good reason, for a story we've done before with other characters. It's so arbitrary and gratuitous, and it's disrespectful to the audience."
The show has reportedly been taken off the air in several countries. China banned it from prime-time television in August 2006, "in an effort to protect China's struggling animation studios". In 2008, Venezuela barred the show from airing on morning television as it was deemed "unsuitable for children". The same year, several Russian Pentecostal churches demanded that The Simpsons, South Park and some other Western cartoons be removed from broadcast schedules "for propaganda of various vices" and the broadcaster's license to be revoked. However, a court decision later dismissed this request.
Critics' reviews of early Simpsons episodes praised the show for its sassy humor, wit, realism, and intelligence. However, in the late 1990s, around the airing of seasons nine and ten, the tone and emphasis of the show began to change. By the early 2000s, with the airing of seasons eleven and twelve, some long-term fans had become disillusioned with the show, and pointed to its shift from character-driven plots to what they perceived as an overemphasis on zany antics. Jim Schembri of The Sydney Morning Herald attributed the decline in quality to an abandonment of character-driven storylines in favor of celebrity cameo appearances and references to popular culture. Schembri wrote in 2011: "The central tragedy of The Simpsons is that it has gone from commanding attention to merely being attention-seeking. It began by proving that cartoon characters don't have to be caricatures; they can be invested with real emotions. Now the show has in essence fermented into a limp parody of itself. Memorable story arcs have been sacrificed for the sake of celebrity walk-ons and punchline-hungry dialogue."
In 2010, the BBC noted "the common consensus is that The Simpsons' golden era ended after season nine", and Todd Leopold of CNN, in an article looking at its perceived decline, stated "for many fans ... the glory days are long past." Similarly, Tyler Wilson of Coeur d'Alene Press has referred to seasons one to nine as the show's "golden age", and Ian Nathan of Empire described the show's classic era as being "say, the first ten seasons". Jon Heacock of LucidWorks stated that "for the first ten years [seasons], the show was consistently at the top of its game", with "so many moments, quotations, and references – both epic and obscure – that helped turn the Simpson family into the cultural icons that they remain to this day".
Mike Scully, who was showrunner during seasons nine through twelve, has been the subject of criticism. Chris Suellentrop of Slate wrote that "under Scully's tenure, The Simpsons became, well, a cartoon ... Episodes that once would have ended with Homer and Marge bicycling into the sunset now end with Homer blowing a tranquilizer dart into Marge's neck. The show's still funny, but it hasn't been touching in years." When asked in 2007 how the series' longevity is sustained, Scully joked: "Lower your quality standards. Once you've done that you can go on forever."
Al Jean, who was showrunner during seasons thirteen through thirty-three, has also been the subject of criticism, with some arguing that the show has continued to decline in quality under his tenure. Former writers have complained that under Jean, the show is "on auto-pilot", "too sentimental", and the episodes are "just being cranked out". Some critics believe that the show has "entered a steady decline under Jean and is no longer really funny". John Ortved, author of The Simpsons: An Uncensored, Unauthorized History, characterized the Jean era as "toothless", and criticized what he perceived as the show's increase in social and political commentary. Jean responded: "Well, it's possible that we've declined. But honestly, I've been here the whole time and I do remember in season two people saying, 'It's gone downhill.' If we'd listened to that then we would have stopped after episode 13. I'm glad we didn't."
In 2004, cast member Harry Shearer criticized what he perceived as the show's declining quality: "I rate the last three seasons as among the worst, so season four looks very good to me now." Cast member Dan Castellaneta responded: "I don't agree, ... I think Harry's issue is that the show isn't as grounded as it was in the first three or four seasons, that it's gotten crazy or a little more madcap. I think it organically changes to stay fresh." Also in 2004 author Douglas Coupland described claims of declining quality in the series as "hogwash", saying "The Simpsons hasn't fumbled the ball in fourteen years, it's hardly likely to fumble it now." In an April 2006 interview, Groening said: "I honestly don't see any end in sight. I think it's possible that the show will get too financially cumbersome ... but right now, the show is creatively, I think, as good or better than it's ever been. The animation is incredibly detailed and imaginative, the stories do things that we haven't done before, so creatively there's no reason to quit."
In 2016, popular culture writer Anna Leszkiewicz suggested that even though The Simpsons still holds cultural relevance, "contemporary appeal" is only for the "first ten or so seasons", with recent episodes only garnering mainstream attention when a favorite character from the golden era is killed off, or when new information and shock twists are given for old characters. The series' ratings have also declined; while the first season enjoyed an average of 13.4 million viewing households per episode in the U.S., the twenty-first season had an average of 7.2 million viewers.
Alan Sepinwall and Matt Zoller Seitz argued in their 2016 book titled TV (The Book) that the peak of The Simpsons are "roughly seasons 3–12", but that despite the decline, episodes from the later seasons such as "Eternal Moonshine of the Simpson Mind" and "Holidays of Future Passed" could be considered on par with the earlier classic episodes, further stating that "even if you want to call the show today a thin shadow of its former self, think about how mind-boggingly great its former self had to be for so-diminished a version to be watchable at all."
In 2020, Uproxx writer Josh Kurp stated that while he agrees with the sentiment that The Simpsons is not as good as it used to be, it is because "it was working at a level of comedy and characterization that no show ever has." He felt there were still many reasons to watch the series, as it was "still capable of quality television, and even the occasional new classic" and the fact that the show was willing to experiment, giving examples such as bringing on guest animators like Don Hertzfeldt and Sylvain Chomet to produce couch gags, and guest writers like Seth Rogen, Evan Goldberg, Pete Holmes and Megan Amram to write episodes. In the season thirty-two episode "I, Carumbus", the show itself makes a nod to these concerns in its credits gag where the god Jupiter notes that "It definitely feels like they're wrapping it up ... any day now." In a 2021 interview with NME, Jean was quoted as saying, "To people who say The Simpsons isn't as good as it used to be, I would say I think the world isn't as good as it used to be. But we're declining at a slower rate."
A counter-narrative since mid-2023 has asserted that—with seasons thirty-three and thirty-four—the show started to become "good again". Screen Rant asserted that season thirty-four was "seen as a return to form" and had been interpreted by reviewers as a "comeback". They then wrote of season thirty-five that there was "no denying that there has been an obvious uptick in quality beginning as early as season 33".
The stereotypical nature of the character Apu Nahasapeemapetilon has been the subject of controversy. Indian-American comedian Hari Kondabolu stated in his 2017 documentary The Problem with Apu that as a child he was a fan of The Simpsons and liked Apu, but he now finds the character's stereotypical nature troublesome. Defenders of the character responded that the show is built on comical stereotypes, with creator Matt Groening saying, "that's the nature of cartooning." He added that he was "proud of what we do on the show", and "it's a time in our culture where people love to pretend they're offended". In response to the controversy, Apu's voice actor, Hank Azaria, said he was willing to step aside from his role as Apu: "The most important thing is to listen to South Asian people, Indian people in this country when they talk about what they feel and how they think about this character." In February 2020, he confirmed that he would no longer voice Apu. Groening stated at the same time that the character would remain in the show.
The criticisms were referenced in the season 29 episode "No Good Read Goes Unpunished", when Lisa breaks the fourth wall and addresses the audience by saying, "Something that started decades ago and was applauded and inoffensive is now politically incorrect. What can you do?" to which Marge replies, "Some things will be addressed at a later date." Lisa adds, "If at all." This reference was clarified by the fact that there was a framed photo of Apu with the caption on the photo saying "Don't have a cow, Apu", a play on Bart's catchphrase "Don't have a cow, man", as well as the fact that many Hindus do not eat cows as they are considered sacred. In October 2018, it was reported that Apu would be written out of the show, which Groening denied.
On June 26, 2020, in light of the various Black Lives Matter protests, Fox announced that recurring characters of color (Carl Carlson and Dr. Hibbert, among others) would no longer be voiced by white actors. Beginning with season 32, Carl, a black character originally voiced by Azaria, is now voiced by black actor Alex Désert. In addition, Bumblebee Man, a Spanish-speaking Latino character also originally voiced by Azaria, is now voiced by Mexican-American actor Eric Lopez, and Dr. Hibbert, a black character originally voiced by Harry Shearer, is now voiced by black actor Kevin Michael Richardson.
