This is a funny, creative horror movie with a lot of guts. Literally.
1. This movie has a weird pedigree - it was made as the result of the third season of the Project Greenlight television series. It was produced by Matt Damon, Ben Affleck, and Wes Craven.
2. It's partly a spoof of the "creature feature" horror subgenre, but it's also a good splatter film itself.
3. It's about a group of people at a bar in the middle of nowhere that get attacked by a group of vicious (and horny) creatures, and they must figure out how to survive. Violence, blood, maggots, vomit, and teeth ensue.
4. The movie plays with your expectations of what a horror movie should be - it turns the stereotypes on their heads. You really can't predict who is going to die and who is going to survive.
5. In a clever twist, the characters are all introduced with a summary of who they are and what their chances are of surviving the movie.
6. The cast is as eclectic as the producers: Balthazar Getty plays a selfish redneck, and Henry Rollins leaves his hardcore punk band far behind to play a self-help guru who keeps trying to boost everybody's morale. And indie actor Jason Mewes has a small part in the movie - playing himself.
7. Some of the editing is so fast that sometimes it's hard to tell exactly what's going on. You never really get a full view of all the creatures. This might be to help hide the fact that it had a small budget and couldn't afford a lot of actual monster shots. But given the pacing and mood of the film, it works OK.
8. The movie is 85 minutes long, and after all the characters are introduced, it's pretty much full-throttle monster action. It doesn't waste much time building up the characters, because most of them die anyway.
9. There's no social commentary or deeper meaning to this movie. It's a simple fun, violent, monster movie that gorehounds should find worth watching.
