I've never read the books which is strange, as usually I read everything and prefer to have read the book before seeing the movie, but I wasn't into the idea of "Twilight" until some friends dragged me to the movie. It was pretty good. Some parts were too sappy for my taste, but overall worth watching. I'm planning to see the second movie when it comes out, though not sure I'll ever get the books. If I can borrow them from a library I probably will.
Vampire stuff - I'm actually in the process of reading Bram Stoker's "Dracula" right now. It's a rainy, stormy day so just perfect for it!
