Critics Consensus

Though there's nothing that offensive about Big Fat Liar, it is filled with Hollywood cliches and cartoonish slapstick, making it strictly for kids.

Really likeable family comedy set in cutthroat Hollywood.

A fitfully amusing romp that, if nothing else, will appeal to fans of Malcolm in the Middle and its pubescent star, Frankie Muniz.

C-

Can’t quite work itself up to affirm that Lying is Bad, but proclaims with great conviction that The Truth Isn’t Overrated.

Although aimed at kids, adults will find Big Fat Liar just as entertaining, giving them a chance to reacquaint themselves with their own "kid within." Goofy, adorable and laughable. Big Fat Liar is one funny film.

Although this movie wasn't a thing like "Holy shit! This is kickass!" It's good, and inspires me to wanting to be an Actor, Producer, Writer and Creative consultant. As I always said: With imagination, everything can be.

Big Fat Liar is one of those early-2000s comedies that feels both weirdly chaotic and genuinely funny at the same time. The whole setup is over-the-top in a way that doesn’t really aim for realism, but that’s kind of the point—it leans into exaggerated situations and silly humor rather than anything grounded. What stands out most is how energetic and fast-paced it is. The comedy ranges from clever moments to outright goofy slapstick, and while not every joke lands, there are enough amusing bits to keep it entertaining. It has that nostalgic, slightly absurd teen-movie vibe that makes it hard to take seriously, but also hard to completely dislike. Overall, it’s uneven but fun in bursts. I’d give it a 5/10—more strange entertainment than a polished comedy, but still worth a watch if you’re in the mood for something light and a little ridiculous.

Filme mais ou menos, o roteiro é fraco, as cenas são mais ou menos, a história é fraca, o elenco é fraco, e ninguém ajuda a melhorar o filme, os personagens são fracos, e o filme deveria ter cenas bem melhores e relevantes, para fazer o filme ser bom
