Absolutely hilarious the sexual curse humor is top notch

A cult classic with many more hits than misses. Fully original and ridiculously funny. Situational low brow at its best. A film definitely not made for the pedantic, pretentious or sheltered. You should love this movie if you have a good sense of humor. The man-child archetype is a comedy staple. They said, "What if we made everyone a man child?" Witty, absurd, oddly relatable at times. This flick punches well above its weight. Sweet car bed.

Filme mais ou menos, o roteiro é fraco, as cenas são mais ou menos, a história é fraca, o elenco é mais ou menos, e ninguém ajuda a melhorar o filme, os personagens são fracos, e o filme deveria ter cenas bem melhores e relevantes, para fazer o filme ser bom.

So idiotic that it ought to come with a complimentary joint, Grandma's Boy is as fleeting and creatively backfiring as its myriad of characters.

Excellent at what it sets out to do. Its that simple. Hilarious and satisfying every time I've watched it.

This movie is so amazing.It is literally my favorite comedy it was a little bit ahead of its time.So I got bad reviews from people who didn't understand the culture. an amazing job done by the cast i wish they would make a second one

One of my favorite movies. Great cast and absolutely hilarious

If you’re high, it’s great. And that’s the point, imo

This movie makes me laugh so hard every time I see it. The entire point is to revert to 12 years old and not think too hard, somehow the other reviewers missed that.

Grandma's Boy is so enjoyable to watch because of its diverse and quirky characters.

One of my favorite movies. Such a good era for comedy, in my opinion.

Brilliantly cast and acted. One of the very few good comedies.

A raucous comedy and a golden story. Certified FRESH!

This movie is nothing short of hilarious! It's so ridiculous that it's compelling... I find it an easy watch for the warp minded and have a filthy imagination. Very very hilarious. If you like anything Seth Rogan is in them I believe this to be your perfect movie night flick with friends.

A classic mid-00s goofy comedy. Sometimes you want to turn your brain off and laugh and Grandma's Boy does that perfectly. Infinitely quotable.

My favorite stoner comedy.

If it where called Grand Mother's Boy he'd have been tied to a chair and beaten with a wooden spoon to learn table manners and how to pay attention to every adult in existence for their lessons of wisdom... Not pampered like a fairy Godmother's puss. On a more serious note where's the game Demonic? You can't show something like that to people and not expect people to not want to buy it. For that ya'll are just a bag of dicks until they can.

One of the funniest stoner comedies ever written. Screw Rotten Tomatoes and the uncultured individuals who don't recognize greatness when they it.

If you do not like Grandma's boy there is something wrong.

One of the best Happy Madison films and not only surprised the company in their success in DVD sales but fans were in love thanks to rental stores at the time. The movie has great irreverent comedy and being a 36yr old stoner myself, I love it. Normally a side character or B actor Allen Covert is great as the lead and really carries the load. Pack a bowl for this and thensome
