I watched this film on a whim and I can tell you from the start that is mostly a waste of time. Mostly, because the vampires in the film, classical as they were, had this twist of high class addicts that tried to stay off human blood, but occasionally failed. There was even a night of the vampires where they just sat there and discussed their condition. This had a lot of potential. Unfortunately the discussion was stale, the basic premise of the film just a spout between eternal sisters (now that is hell) and nothing else.
The cast was also full of potential. Milo Ventimiglia is a decent actor and rather good looking; I bet he will do increasingly well. Roxane Mesquida is hot as hell, especially in the role of the out of control psychotic bitch. Michael Rapaport, poor guy, had a lot going for him but now is just a fat nobody playing ridiculous roles. However, I am pretty sure this cast could have done a decent job with a good script. Alas, this was anything but one.
Add to this the really bad direction, the weak effects, the obsolete camera techniques and you get a movie that looks made by a student for a cinematography exam. Just avoid it.
