How bad is it? It borders on the unwatchable.
Should you see it? Absolutely not.
This Roger Corman-produced sleaze is about as bad as vampire films get. There's a dwarf with a spider tattoo on his head, hamster eating, someone throwing up their internal organs, some faked Nepal scenery, quotes from better movies, poor make-up (no fangs on these vampires), badly done strip routines and a director who tries every bad camera trick to try to be visually interesting.
