It took a while to get going, but after the set up, the jokes start coming pretty regularly and some of them are pretty funny. There is not, however, one scene in this movie that is even close to as funny as the first scene in Super Troopers.
There seems to have been some confusion as to whether or not this was a horror movie. I cannot begin to comprehend how anyone could see it as such. Gore does not equal horror. Is it scary? No. Is it supposed to be? No. It is just a horror parody, much like the "Scary Movie" series but not as broad and zaney.
I do really like Broken Lizard as a comedy ensemble. They play off of each other really well. The timing is great, the humor is silly. Each one of them really has something that compliments the group as a whole. I also really like quite a bit of the writing. Some of it is kind of stupid, yes. But it always stays away from all Hollywood cliche and it sounds fresh - as in, not stale, like most of the Tinseltown cookie cutter crap that calls itself comedy.
If you liked Super Troopers, you will like this movie less, but you will still like it. Good, silly, fun from good, silly comedians.
