Robert DiNero definitely surprises everyone with his portrayal of a grandpa who just lost his wife. If you thought he was funny in the Meet the Parents franchise, then you have to see this. Don't take your kids though; it's rated R for a reason lol. That being said I was actually somewhat impressed with Zac Efron's performance although Robert DiNero steals the spotlight for 90% of the film.

This was a dirty comedy with lots of laughs from beginning to end! It was somewhat predictable, but enough little surprises to keep you interested and laughing. Definitely NOT for children though. I really enjoyed it!

One of the most hilarious movies in the last years. Robert De Niro nails it. We could't stop laughing during the whole film.

It was very funny from the start keep you entertain.
