I fucking love this series and despite poor reviews found this one to be just as fun as the others. Sure some scenes don't make sense and the writer's took a few days off, but there is plenty of great stuff mixed in and a blast ending I should've seen coming but somehow didn't.
If you didn't like 1 or 2, stay away as there's nothing to change your mind here. If you like the first 2, odds are you'll at least enjoy this. I did notice they ignored the ending of part 2 to make this work (once again leading perfectly into part 1, just a bit differently). More gore. more girls, more guns, and more people being splattered. What else could one ask for from these films?
