"The bad thing about 'A Guy Thing' isn't the talent of its stars but the warmed-over triteness of the material they're forced to work with...In place of real romance and comedy, it offers worn-out clichE`s, by-the-numbers platitudes, and frozen smiles that few in the audience will want to imitate." -- David Sterritt, The Christian Science Monitor

"In eNA Guy Thing,iL Jason Lee, the former Kevin Smith slacker who has flirted with leading-man status ever since he played Stillwater's lead singer in eNAlmost Famous,iL seems to have been bitten by a vampire who sucked out all his prickly charisma. You see the promise of stardom dribbling through his fingers." -- Owen Gleiberman, Entertainment Weekly

"Most of the meager charms of the chaotic romantic farce 'A Guy Thing' spring from the deft comic contortions of Hollywood's ultimate nerdy sidekick, Jason Lee...'A Guy Thing,' directed by Chris Koch, lives up to its title in its haphazard treatment of its women. Ms. Blair's one-note fiancE`e is nothing more than a walking danger signal. And the dull, underwritten role of Becky is an unfortunate misstep for Ms. Stiles, a serious actress from whom comedy does not seem to flow naturally." -- Stephen Holden, The New York Times

"'A Guy Thing' is by no means the worst movie ever made; given that I missed the recently released 'Just Married,' another comedy about being young, stupid and in and out of love, it's a good guess that it isn't even the worst movie of the month...Did it really take four Writers Guild members (Greg Glienna, Pete Schwaba, Matt Tarses and Bill Wrubel) to write a joke about some soiled underwear?" -- Manohla Dargis, The Los Angeles Times

"Evidently, Glienna and director Chris Koch (the genius who helmed 'Snow Day') decide, early on, it's not enough to rely on characters and intriguing situation comedy...Give us jokes about diarrhea! That's what everyone wants. Or do they? Check the Monday morning box office returns to find out." --Desson Howe, The Washington Post

"The stars have little opportunity to engage their characters. The gang-written screenplay and Chris Koch's artless direction turn their scenes into a series of broad, overplayed comic sketches. There are funny moments here and there, but oh, the agony of what's in-between." --Jack Mathews, The New York Daily News
