I saw this on the weekend and really enjoyed myself. In a nutshell, it's about middled aged guys with shitty lives who wish they could go back in time to their college days. I laughed a lot. While my Dad laughed I was surprised when he said he didn't like it as a movie. Ok, so it didn't make total sense, but its comedy. I was just glad to see a comedy where it remains funny throughout unlike some movies where the comedy is all in the trailer. I'll be surprised to see a better comedy this year.
I will point out that this kind of comedy is not for everyone.
Cuz it was a retarded movie with barely any jokes, disgusting scenes and a retarded plot. There was a tiger in their bathroom HOW IS THAT FUNNY? WHY WOULD YOU LAUGH AT THAT? Hangover sucked unlike hot tub time machine which was very very funny.
I gotta go with Joseph here, the Hangover was nothing else than a really bad gross out movie with a Mike Tyson cameo and random stuff happening for no reason, followed by a plot which you think should turn out clever on some kind of level but instead just slaps you in the face...
