Even though it is last on my list for a movie about vampires.
Dracula 2000 has the best origin because it uses more facts of history that we can relate to and the the legend of vampires' facts fit into it nicely. When the movie showed(to not spoil for anyone who hasn't seen it) where he came from and who he was. It was one of those feelings that you get when a Palpatine tells a young Anikin "We'll watch your career with great interest."
