I picked up the blu @ BB a few weeks back, and I love it. It's no Super Troopers or Beerfest, but it's damn funny. They actually take a lot of shots at themselves in this script.
Jay and his multiple personalities was hilarious, Duncan was awesome, and it was a tight little script, even if predictable. It wasn't as wild as previous films of theirs. but you've gotta realize this is a different type of story than their previous attempts. This story takes place in the span of one night, where all the other movies are over longer time periods, so there can be more hijinks.
