    A surprisingly entertaining movie -- one of those good-hearted comedies like "Spy Kids" where reality is put on hold while bright teenagers outsmart the best and worst the adult world has to offer. It's ideal for younger kids, and not painful for their parents.
  2. 70
    A hilarious film for anyone who remembers lying as a kid-- and anyone who wants to see a movie that's just plain fun.
  3. An innocent comedic revenge fantasy that somehow manages to be sweet and wickedly satisfying at the same time.
  4. The film gets snaps just by attempting the high road, and should be enjoyed by its target audience.
  5. A harmless and mildly amusing family comedy.
  6. 60
    Fresh-faced leads Muniz and Bynes are charmers, Giamatti makes Wolf into a splendidly loathsome adversary, and the film is refreshingly free of bodily function jokes.
  7. Plays so flat, so to close its "movie message" formula, that it seems as if we've seen this movie before.
  8. The result is a children's movie that's almost worth seeing even when not accompanied by a child. It's certainly a painless experience, and at times it's quite funny.

    Not so admirably, the film feels at times like a giant commercial for Universal Studios.
  10. Big Fat Liar becomes a progression of increasingly elaborate slapstick stunts, in the brutal, noisy "Home Alone" vein, in which the complexity of the pranks rarely yields a commensurate comic reward.

    Generally succeeds. But with just a bit more effort the movie might have been funnier and a lot more fun.
  12. If Ms. Bynes keeps going in this direction, she can conceivably develop a gallery of characters as rich and varied as Tracey Ullman's.
  13. The movie scores some laughs, all of which come from the expert Giamatti.
  14. 40
    Screenwriter Dan Schneider and director Shawn Levy substitute volume and primary colors for humor and bite. Granted, it's a kids' flick, but kids today have enough savvy about the movie industry to report for Variety.

    Offers little in the way of pleasure, even to its target audience -- the easily pleased and undemanding.
  16. What starts as a cute premise crashes faster than a skateboard with an oak branch shoved between its wheels.
  17. There are lame comedies, and then there is Big Fat Liar, which is so lame that it merits its own reserved parking space.
  18. 25
    Loud and unfunny, this cheesy-looking farce is mostly an excuse for a series of plugs.
  19. 25
    A lame collection of dumber-than-dumb gags, the quality of Big Fat Liar is on par with that of the worst television sit-com gorged to four times its normal size.
  20. How appealing is Muniz, taking a break from ''Malcolm in the Middle,'' a day job he should by no means let go of?

    Old people are made to look ridiculous; clowns are brutalized; characters talk in rapid-fire vaudeville shtick.
  22. 20
    Big Fat Liar's screenplay, co-written by Robbins and fellow Head Of The Class alumnus Dan Schneider, is a model of comic inefficiency. Like a Rube Goldberg contraption, it goes to excruciating, wildly implausible lengths for the flimsiest of payoffs.

    Though Muniz and Bynes make a somewhat likable team, their funniest skills are dampened by the material's insistent stupidity.
  24. A bland, obnoxious 88-minute infomercial for Universal Studios.

  2. Man, it's been 10 years since Big Fat Liar released to theaters. One of my favorite moment in the movie was Marty Wolf turned his face blue, Blue as in Blue (Da Ba Dee) by Eiffel 65. And then he was pummelled by a group of birthday kids and the OH MY GOD!" I really love the ending when he dressed as a clown and that kid kicked him in the nuts. That was awesome. Can't wait to get it on Blu-Ray soon. Full Review »
  3. The unexpected plot direction and great performances pay off and this is actually a smart movie that families can enjoy.
