I Love Hellsing Ultimate

Hellsing Ultimate... Probably one of the best series, hands down. Sure, the story is a tad bit thin. And the wacky mix of vampires, Nazis, and Lovecraftian themes might not be for everyone, but it's a great little concoction if I do say so myself. Music could be better, especially when compared to the first anime that came before it, but it's still got a lot of memorable and catchy themes.
