This movie is definitely one to beat for 2016! Funniest movie I've seen in a long time! ZAC Efron and Robert Dinero were classic comedian who brought on a reality of our younger generation vs the older which were not so different! Great one liners hilarious scenes! Can't wait to see again! Left me in tears!

hilarious all the way through with lots of surprise moments! de niro is in rare form!

Very funny in a raunchy way. What do you expect from a movie titled "Dirty Grandpa".

I was surprised that De Niro and Efron would be such a hilarious duo. I've never heard De Niro use words like that!!!!! This movie was one of the funniest movies I've seen in years. So glad I saw this screening. That you for the tickets!
