I mostly agree with this review Flo.
The effects, lighting, and soundtrack are indeed awesome (specially the lighting!), the performances of Benicio and Anthony are outstanding as always, and totally agree with the "not for weak stomach" part, which is all good with me, very graphically violent, but elegant at the same time, is hard to explain, but they did a great job with the blood bite sh*t!!! And the transformation part .... oh so disgusting!! (good disgusting though LOL)
The story itself, on the other hand, not very good IMHO, a bit boring and so predictable, but all the other stuff make this movie very much worth watching!
