I'm not entirely sure that this is a harcore Hellsing ripoff, this is based off a series of novels; it's also being made into a manga. Anyways you've got to give it more than an episode. At least wait for some form of a plot to reveal itself.

Monkeyman: You definitely do not need to watch Hellsing for this series, maybe you'll enjoy it more if you don't, but you should still watch it as it is a pretty good and short anime.

Oh, and if anyone is interested in reading the manga you can find it at either of the following sites:
