Critical response
On the review aggregator website Rotten Tomatoes, the film holds an approval rating of 56% based on 36 reviews. The website's critics consensus reads, "With a throwback 1930s vibe, this screwball romantic comedy is perfect for One Fine Day of folding laundry." Metacritic, which uses a weighted average, assigned the film a score of 56 out of 100, based on 21 critics, indicating "mixed or average" reviews. It was considered a commercial disappointment by Twentieth Century Fox.
Janet Maslin of The New York Times wrote, "A 50's romp with a few glaring 90's touches (dueling cellular phones, frazzled single parents), One Fine Day makes for sunny, pleasant fluff. Both stars are enjoyably breezy, and there's enough chemistry to deflect attention from the story's endless contrivances... he's [Clooney] such a natural as a movie star that he hardly needs false flattery. Ms Pfeiffer, meanwhile, shows a flair for physical comedy."
Roger Ebert of the Chicago Sun-Times wrote, "'Cinema is the history of boys photographing girls.' Or so Jean-Luc Godard is claimed to have said. I thought of his words while watching One Fine Day, an uninspired formula movie with another fine performance by Michelle Pfeiffer. She does everything in this movie that a much better movie would have required from her, but the screenplay lets her down... Pfeiffer looks, acts and sounds wonderful throughout all of this, and George Clooney is perfectly serviceable as a romantic lead, sort of a Mel Gibson lite. I liked them. I wanted them to get together. I wanted them to live happily ever after. The sooner the better."
Rita Kempley of The Washington Post wrote, "Director Michael Hoffman, whose idiosyncratic portfolio includes the period comedy Restoration and the spoof Soapdish, sets a mellow pace and alternates old-fashioned split screen with crosscutting to enliven the many phone scenes. If the stars don't click, of course, nothing else matters. Happily, Pfeiffer and Clooney, now officially a movie star, not only click, they send off sparks."
Kenneth Turan of the Los Angeles Times wrote, "One Fine Day is fortunate in its casting. Not only does it have Michelle Pfeiffer, whose gift for this kind of business was visible as far back as Married to the Mob and The Fabulous Baker Boys, but it marks the emergence of George Clooney as a major romantic star... Still, despite feeling like its moments have been micro-managed for maximum audience response, One Fine Day often passes for a pleasant diversion. But with actors so suited to each other, it's too bad the film didn't give them more original material to work with."
Edward Guthmann of the San Francisco Chronicle wrote, "We've seen it before, but Pfeiffer and Clooney do everything in their power to make it seem fresh and delightful. That's ultimately not enough, and even though the stars have some chemistry and Pfeiffer delivers her usual spotless performance, One Fine Day never manages to be more than a harmless, forgettable time-filler."
Rob Nelson of the Boston Phoenix wrote, "Privilege and coincidence have always been central to screwball comedy, but the speed of crosstown travel here rivals Die Hard 3 for plausibility. And it's these convenient shortcuts that waylay the film from examining the condition it purports to critique: that is, the '90s compulsion to drive at full throttle."
