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: For a first film in a proposed series it achieves the right balance. It is done with style and class showing Modesty's early days as a refugee and the start of her rise to power in the criminal world. I think it is a very honest/true portrayal of her character exactly as the writer Peter O'Donnell intended. Alexandra Staden as Modesty is stunningly beautiful and an excellent choice. She acts very convincingly as the tough survivor with an exterior of cool/intelligent/innocence. And full marks to Tarantino for choosing an unknown actress for the role - much more believeable to have a new face creating the part. I'm looking forward to the next film. Question: is it a negative review?
no

Review: Some genre films need to be dressed up. This one was an exception. Taken on its own merit, it's a dressed down version of the horror genre film. With minimal special effects, it manages to be a psychological study of sorts, with a simple yet existential theme - who gets hit by the bus, and why her? It's not a great film, yet because there is little contrived about it, the story works. Subtle, and all about the interactions of the characters. Actually, there is one contrivance in the opening scenes, but it may have been placed there to simply set the tone for what's to come. I very much appreciate the balance of male and female energy, and would not recommend this story to anyone interested in more than people reacting to a physical and psychological challenge. You will enjoy the film if you have some empathy, value the need for a bit of adventure in your life, and wonder "What would I do in this situation?" Question: is it a positive review?

yes
