Oh dear. What a mess. Doubly sad, when the poster is so cool. The premise isn't half bad either. A bunch of aliens have taken over a hospital, where they're draining the blood of young hot-blooded teenagers. Some local yokels are responsible for abducting the youngsters and delivering to the aliens, but they keep messing up. The bodies are too mangled or not fresh enough. And not just that...the mission is almost over and time is running out.
Sadly, it's not running out quickly enough. Bad, bad, baaaad film.
