I'm not saying this is a bad flick, but if you miss this you haven't missed a thing. Jude Law's "Immortal" is far better and far more interesting to look at. Abel Ferrara made "The Addiction" in 1995, which seems to have "inspired" this one. So non Bram Stoker - Hammer Horror vampires are hardly an original concept. It is a brutal, ugly movie made up with stock characters: the hooker with a heart of gold, the unwilling blood addict, the psycho, punk kids, and totally non present police. I mean there is a crime wave of hookers being brutally murdered ala Jack the Ripper, yet not even a stock bobby trying to restore order.
Mining the seedy underworld of strip joints and prostitution in Dickens like modern London, which seems to be old dark alleys, is nothing we haven't seen before. Mining drug addiction with intelligent but routine observation about addiction that one can find at any 12 Step meeting or a hundred horrors of drug movie is hardly inspiring. Ditto for non traditional vampires. So there is nothing groundbreaking or original in this movie. I saw bits and pieces of previous films spliced into this one. So it is hard to pretend this is something brave and new that is going to knock your socks off. It is full off some really brutal violence, though nothing exceptional by today's standards and the sexuality is there and is probably the only redeeming feature of the flick, Tarantino like dialog is routine too these days. Just cut and paste some lines in MS Word and viola! This is an indy movie as far as improvisation, location shots and low budgets go, but at heart it is a cheap exploitation flick with plenty of brutal violence, psycho behavior and some soft core sex thrown in to pander to sophistos by glossing it over with a patina of some intelligent dialog. In my book, if you shoot for some intelligent and arty effect but end up being mainly ugly, common, derivative and brutal, then you are better off just watching some mindless Alien tear them apart type flick or some cheesy Hammer high Goth vampire flick cause at least you be getting an honest product.
