First hour great but then drops off

Rating: 5/10 (9 September 2011)

The 1st hour of this movie is hilarious. Its humor is similar to the movie "Hangover" except there are slightly less obscenities. There is still vulgarity so if U don't like this in a movie your probably better off watching something else. However after the main characters leave Las Vegas, U may as well shut off the DVD player. The movie becomes deranged after Vegas. That is really where the movie falls short.
------ MINOR SPOILER
For example, one of the main characters goes back to his dictatorial girlfriend and they live happily ever after. How is this comedy?
------
This could've been a great movie from beginning to end. However its humor stayed in Vegas.
