I would have to say the best movie with a vampire I have ever seen is probably Let the Right One In. It was fabulous; I loved it. If you're going to play around with vampires as being "good," then THAT'S how you do it, people. With solid, fascinating characters and moral ambiguity. By being bittersweet, rather than saccharine. Twilight wishes it could be *half* as awesome as this movie. But it's nowhere even close.
