Killer Party goes from zombie movie to music video to slasher to ghost story to possession film to frat comedy so many times during its runtime that you might want to wear one of those airplane pillows to prevent whiplash, but it balances all these genres and subgenres better than any film should be able to and it's never dull. It keeps things moving fast enough so you don't have a lot of time to think about how a lot of it doesn't make much sense.
