And Hellsing is awesome.
Seconded. The anime series is pretty good on its own, but if you want to become a hardcore fan you'll need to watch the OVAs and/or read the manga.
I must warn you: it is very violent and contains foul language, and the OVAs and manga contain imagery that some people may find offensive (*cough*Millennium*cough*).
If you like Hellsing, another good one is Trinity Blood. There are three versions, each one telling separate stories than the others: anime, manga and novels. I personally prefer the anime and I kind of like the manga, but I have too much trouble sitting still to read the novels.
