Night of the Creeps is a fantastic movie to watch in many different situations: with friends, at a sleepover, in the middle of the night, in the middle of the day, and so many more.
It's an easy to watch flick, and it contains the right balance of horror elements, gore, campiness, humor, and absurdity to make each viewing as enjoyable as the last. It's got a touch of body-stealing aliens, a touch of zombies, a touch of traditional serial killer, all mixed with all the fun that can come from being placed in a sorority house.
Sure, it's not downright frightening, and it's not necessarily an utterly funny movie like a comedy, but the balance it strikes between the two is where the beauty shines through.
