Reception
Pokémon 4Ever received generally negative reviews from television critics. Some critics called it "predictable" and "disappointing", while others stated that "the viewers won't be disappointed". The film received a 16% rating on Rotten Tomatoes, based on 38 reviews, the lowest of the Pokémon film series (original), with the consensus reading, "Only for diehard Pokemon fans". It received a rating of 25 out of 100 (signifying "generally unfavorable" reviews) on Metacritic from 16 reviews. In a review of the film, Dann Gire of the Daily Herald said that "nothing feels more desperate than a movie that tries to extort emotions from young viewers. That happens in the animated Pokémon 4Ever, in which colorful characters stand around crying over the shriveling corpse of a magical creature called Celebi. The movie has emotional warmth of tin foil, mainly because it never establishes connections among the characters, or between the characters and viewers".
Tenley Woodman of the Boston Herald said that "Fans 4Ever would be a more appropriate title for the film because Pokémon enthusiasts likely will be the only ones satisfied by the fourth big-screen installment of this Japanimation craze". He added that "the story line is solid, with Pokémon's proxy-fighter premise pieced together for first-time viewers. However, the film lacks the spark needed to make it a must-see flick". Robert Koehler of Variety said that the "script by Hideki Sonoda is thin in terms of levels of action and adventure, and suffers from last minute padding with one ostensible ending following another. A clever notion to pop up in the larger Pokémon epic, however, is the suggestion that The Professor (the Pokémon trainers' long-term, reliable guide to all things Pokémon) is actually Sam, now grown up in the present". He then added: "Yank voices – holdovers all from the past films – remain as irritating and overly emphatic as ever". Tasha Robinson of The A.V. Club criticized the movie's pacing stating that "In the concrete, though, it's deadly dull. There's no point to prolonging the inevitable, except to pad the movie out to its barely feature-length run time". Lawrence Van Gelder of The New York Times stated that when "it comes to entertainment, children deserve better".
Loren King of the Chicago Tribune gave the film a generally positive review, saying: "The latest installment in the Pokémon canon is surprising less moldy and trite than the last two, likely because much of the Japanese anime is set in a scenic forest where Pokémon graze in peace. The backdrop provides a welcome respite from the ear-, eye- and mind-numbing Pokémon action. And the time-travel plot, though less than inspired, is still tolerable enough for adults accompanying kids". He added that "like most Pokémon tales, this one offers lots of exposition and clunky dialogue, but also counters the expected mayhem with a sweet-sided story about friendship and peaceful creatures who prefer to live far from the madding crowd". Angel Cohn of TV Guide said in his review that "the story is a bit predictable and the characters given to restating the obvious (presumably for the benefit of very young viewers), but overall this third Pokémon sequel is surprisingly entertaining, and a mystery surrounding Sammy's identity provides an interesting twist. The film's flat, traditional anime aesthetic is perfectly suited to the look of the bold, cartoon-like creatures, though the animators switch to a more CGI-influenced look for portions of the final battle sequence. While well done, these scenes feel jarring and out of sync with the rest of the film. Quibbles aside, children and adults enamored of all things Pokémon won't be disappointed".
