Some say this isn't a film about vampires at all. However - I think it is! Okay, the characters aren't vampires in the traditional sense, but in the movie's pre-sequence they quote that "some people believe that the sleepwalkers were the origin of the vampire myth". They have fangs (okay, a lot of film monsters do have them), they are shape shifting between monster and man and they kill their prey by sucking the life energy from them. Consider this: is the blood, which their more "traditional colleagues" suck, not just a synonym for life energy? Well... after all, it's a well done horror movie with at least some vampire-like characters, and it's good fun. As a bonus you will find directing icons like Tobe Hooper, John Landis and Clive Barker in short guest roles!
