When he and his roommate can't pay their rent, video game creator Alex (Allen Covert) finds himself homeless and moves in with Lilly (Doris Roberts), his wacky grandmother. Lilly and her elderly pals like to hang out in front of the television all day, but their constant presence puts a damper on Alex's social life and pot smoking. Alex wants to court co-worker Samantha (Linda Cardellini), but he's preoccupied by a rivalry with another game designer, so the would-be relationship is in limbo.

Critics Consensus

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

Grandma's Boy | Rotten Tomatoes (1) Joshua Katzman Chicago Reader The sex, fart, and pot jokes come so fast and furious that a white flag seems the most appropriate response. Aug 15, 2015 Full Review Grandma's Boy | Rotten Tomatoes (2) 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. Rated: D+ Sep 23, 2006 Full Review Grandma's Boy | Rotten Tomatoes (3) Marc Savlov Austin Chronicle 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. Rated: 2/5 Jan 15, 2006 Full Review Grandma's Boy | Rotten Tomatoes (4) Heather Boerner Common Sense Media Absolutely dreadful and offensive comedy. Rated: 1/5 Dec 18, 2010 Full Review Grandma's Boy | Rotten Tomatoes (5) Felix Vasquez Jr. Cinema Crazed So filled with untapped laughs, potentially interesting sub-plots and fails in every single aspect in a mostly laughless stoner comedy. Apr 29, 2009 Full Review Grandma's Boy | Rotten Tomatoes (6) Ethan Alter Film Journal International 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.

J H If you’re high, it’s great. And that’s the point, imo Rated 5/5 Stars • Rated 5 out of 5 stars 01/12/25 Full Review Melissa H This movie makes me laugh so hard every time I see it.
