Hellsing is one of my favorite horror anime. It's an awesome story with a really great cast. Who doesn't love strong, capable female characters, an awesomely powerful vampire and an old guy who fights with dental floss? The story takes place in merry old England, only it’s not so merry at the moment. England is being assaulted by waves of “fake” vampires. A good thing the royal family saw fit to install an official vampire hunting organization in days of yore.
