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 negative review?
yes

Review: Absolutely one of the worst movies of all time.Low production values, terrible story idea, bad script, lackluster acting... and I can't even come up with an adjective suitably descriptive for how poor Joan River's directing is. I know that there's a special place in Hell for the people who financed this film; prolly right below the level reserved for child-raping genocidal maniacs.This movie is a trainwreck.(Terrible) x (infinity) = Rabbit Test.Avoid this at all costs.It's so bad, it isn't even funny how bad it is. Question: is it a negative review?
yes

Review: Sorry. Someone has to say it. This really is/was a dull movie. Worthy perhaps, but dull nonetheless. I nearly cried with boredom when watching it. The acting is pretty dire, the story drawn out and predictable, the score and camera-work totally standard and unexciting. It's one of those movies you are not allowed to hate (becase it is about disabled people) but hate it I suspect nearly everyone does. It is interesting that critics have been so kind to this movie. I suppose they too are not allowed to be objective. This was made to win awards - which I remember it duly did. But it was neither interesting nor entertaining. I haven't seen the play so cannot compare. Question: is it a positive review?

no
