Lou Lumenick, New York Post: Nicholaus Goossen, another Sandler protege, makes an inauspicious directing debut with this limp collection of cliches larded with product plugs. Read more
Nathan Rabin, AV Club: Hilarity fails to ensue in the workplace or at home, in spite of the late introduction of a fighting, driving monkey. Read more
Ty Burr, Boston Globe: No one here has the slightest idea what being elderly actually means or that old folks may once have been (and may still be) far hipper than the young men and women looking at them with fond incomprehension. Read more
Joshua Katzman, Chicago Reader: The sex, fart, and pot jokes come so fast and furious that a white flag seems the most appropriate response. Read more
Christy Lemire, Associated Press: If you're a video game geek and/or a stoner, Grandma's Boy isn't a comedy -- it's a documentary. For everyone else, it's an interminably flat, one-joke movie with admittedly a couple of decent laughs. Read more
Gregory Kirschling, Entertainment Weekly: [The film] does a very thorough job of reducing every recognizable member of the cast to probable career lows. Read more
John Monaghan, Detroit Free Press: Grandma's Boy is a brain-dead stoner comedy from Happy Madison Productions that was coproduced by Adam Sandler. Rarely has so little been done with so little. Read more
Gene Seymour, Newsday: The kind of laid-back goofball comedy custom-designed to chase away any self-respecting respectable person and play to the good-natured slackers out there in the dark. If you're among the latter, you've found a home. If you're not, you have been warned. Read more
Lisa Rose, Newark Star-Ledger: While '06 is still young, chances are, 12 months from now, Grandma's Boy will rank as one of the year's worst comedies. Munich offers more laughs. Read more
Jami Bernard, New York Daily News: Even silly fun needs serious talent behind it. Read more
A.O. Scott, New York Times: I did manage to be more tickled than annoyed at some of the movie's dumb, crude attempts at humor. Read more
Robert Abele, L.A. Weekly: What distinguishes this freewheeling, strangely honest comedy (directed by first-timer Nicholaus Goossen) is its puff-and-pass-it-along view, an inviting, goofy-grin attitude toward insular losers. Read more
James Berardinelli, ReelViews: This is one of those movies where you stay rooted in your seat just to see how bad it can really get. And every time you think it has hit the bottom, the filmmakers find a passage taking them lower. Read more
Peter Hartlaub, San Francisco Chronicle: Grandma's Boy is an Adam Sandler comedy without Adam Sandler, which is kind of like getting a root canal without the dentist. Read more
Liam Lacey, Globe and Mail: An Adam Sandler movie without Adam Sandler, it turns out, is not necessarily an improvement. Read more
Peter Howell, Toronto Star: I may require therapy after seeing this. Read more
