Critics Consensus

A gross-out comedy that's more gross than comedic, Grandma's Boy is lazy and unrewarding.

The sex, fart, and pot jokes come so fast and furious that a white flag seems the most appropriate response. Go to Full Review Nathan Rabin AV Club Sep 23, 2006

Hilarity fails to ensue in the workplace or at home, in spite of the late introduction of a fighting, driving monkey. Go to Full Review Marc Savlov Austin Chronicle Jan 15, 2006
2/5
It's gross, it's cheesy, and it's baked beyond all reasonable limits, but this everything-and-the-kitchen-sink comic soufflé still manages to be goofily entertaining beyond all expectations. Go to Full Review Heather Boerner Common Sense Media Dec 18, 2010
1/5
Absolutely dreadful and offensive comedy. Go to Full Review Felix Vasquez Jr. Cinema Crazed Apr 29, 2009
So filled with untapped laughs, potentially interesting sub-plots and fails in every single aspect in a mostly laughless stoner comedy. Go to Full Review Ethan Alter Film Journal International Mar 1, 2007
Even if you aren't under the influence, you might find yourself chuckling at various points during the movie, if only in disbelief at some of the things the cast is asked to do. Go to Full Review Read all reviews

Tom R @RT95671326 Jul 22, 2026 Pretty hilarious movie, but if you don't smoke a lot of weed you really might just roll your eyes. Its a movie made for people who are complete stoners. Lol. See more Alex G @RT15582241 Jul 19, 2026 Timeless Stoner comedy. People downvoting just don't like gamer or stoner humor and that's cool. See more Ben W @TacoTacoBurrito Jul 10, 2026 This is literally the worst movie I have ever seen. I was once a 14-year-old stoner, and even then I don't think I would have laughed once. See more Drinx W @MrDrinx Jul 8, 2026 Top notch writing and comedy. So many quotable parts See more Affleberry F. @JimSnow Jun 26, 2026 Very underrated comedy. Definitely worth the watch. See more tm11999 M @tm11999 Jun 16, 2026 who in sam hill uses the word "inappropriate" in a comedy? the 15% critics should go soak their collective heads. i loved shirley jones when she was a baby and i loved linda cardellini when she was a baby too. funny flick about the times. you can watch this.
