From Dusk till Dawn. Loved that movie as a teen, the ultra cool George Clooney, the kinda hot Juliette Lewis (in that movie at least), the Salma Hayek scene... And yes, it's a vampire movie... at least the second part lol.
I don't like vampire (or any monster) movies at all and I don't get the appeal for them. But this movie starts as a crime thriller / road movie and once you even get to see a vampire you're so far into it, that you wanna see it to the end. I had the pleasure of watching it unspoilered, so what a surprise that was lol.
I kinda like Vampires from John Carpenter too, was my first DVD ever. It also had that south western kind of setting. Maybe that's why I like these two.
