Grandma's Boy is about a thirty-something pot-smoking video game tester who has to move in with his grandmother and her two friends after losing his apartment.  Yeah, it's about as good as it sounds.  The premise has promise, but everything is so uninspired and surprisingly dull.  The movie is a series of jokes about pot and old people.  Happy Madison, Adam Sandler's production company, is the "brains" behind the movie.  This means that many of the actors here are Sandler associates, both from Saturday Night Live and his movie career, and much of the humor is the same.  The largest difference is that Sandler usually tries to have some sort of sweet center to his movies to balance the stupid humor.  Grandma's Boy has none of that.  It's just stupid.  It makes one long for Sandler, which, well, is just scary.

Alex (Allen Covert, The Longest Yard, 50 First Dates) is forced to move in with his grandmother Lilly (Doris Roberts, Dickie Roberts, All Over the Guy) when he's evicted from his house after his roommate spent the rent on Filipino hookers, and he has an, uh, uncomfortable experience at his friend and co-worker Jeff's (Nick Swarsdon, Malibu's Most Wanted, Pretty When You Cry).  To avoid looking like a total idiot, he lies to everybody and tells them he's living with a female friend and her two roommates, implying that's he's having sex with them every night.  In reality, he's doing their chores, which leaves him exhausted at work.

And at work, Samantha (Linda Cardellini, Brokeback Mountain, Jiminy Glick in Lalawood) is brought in to help get the testing for a hot new game back on track.  Each employee is given levels to test, but because Alex is so tired, he cannot do the work.  It's a shell of a plot by Barry Wernick, Covert, and Swarsdon.  This feels more like something between a sitcom and a series of related sketches.  Most of them revolve around pot or Allen's coworkers discovering that he's living with his grandmother.  Director Nicholas Goossen does very little with the premise.  Ooh, let's throw a big party with the grandmothers!  Yeah, whatever.

Instead, they parade around a host of one-dimensional characters, all with some trait meant to elicit laughs. Joel David Moore (Dodgeball, Raising Genius) is the genius video game designer who dresses like he's Neo from The Matrix and often speaks like a robot. Kevin Nealon (Daddy Day Care, Good Boy!) is the weird boss. Peter Dante (50 First Dates, Stuck on You) plays Dante, the guy who supplies everybody with pot. Grandma's Boy goes through its paces in a dull manner, with many of the situations not as funny as one would expect. A grandmother smoking pot is funny for a few minutes, but that's it. The eventual love story that develops between Samantha and Alex is forced and not credible, and worse, Alex is not that interesting a person. And Grandma's Boy is not that interesting (or funny) a movie.
