Review: not your typical vamp story, not bram stoker or anne rice here. a truly original vampyre story. these vampyres are genetic mutants who the sunlight don't bother. they are pure evil to. the film is not perfect. many of the actors are clearly amateurs. the two leads who play van helsing and rally the vampyre chick are pretty good though. the film is intensely violent which may disturb some people. also it is loaded with scientific detail that many will find hard to understand and may get bored with. i was sold on the clever storyline and the couple good performances. no telling how successful this film could be if they had a bigger budget and it got mass distribution Question: is it a positive review?
no
