If you liked the original, you'll probably like this film, but I have to admit the film irritated me somewhat. It was a little too knowing, cocky and self-refferential (storylines are carried over from previous films).
In addition it came across as a bunch of guys having a good time and that irritated me. Don't get me wrong, I don't want the actors to seem miserable while they made the movie, but I don't want to get the sense that they made the movie because they like making movies together either, and I got that feeling during the movie. That irritates me no end because I don't want feel like I'm missing something when I shell out money to see things (and I got that feeling here).
