The first half of this film is like anything you'd expect from Quentin Tarintino and Robert Rodriguez: cool 70's soundtrack, snappy dialogue, really good editing, lots of violence, and a slightly unconvincing role by QT himself. I thought it was disturbing, stylish and pretty good for the first half, and was enjoying it.
And then they get to the Titty Twister, where there are lots and lots of vampires and lots of blood and nudity, and lots of fighting, and, for me, it just went completely downhill. It felt silly and just inappropriate from what we'd seen at the beginning, and I actually got a little bored.
That being said, I really liked Harvey Kietel's performance and George Clooney was much better than I'd thought he'd be. Plus, Salma Hayek is one sexy kitten.
So yeah, half a good film. If you love over the top vampire films though complete with dated effects, then go for it, because you might just like it
