Saw the first 4 episodes and I gotta say, as somebody who's never played the game I really do enjoy this show. I guess it reminds me a lot about Hellsing Ultimate but this show brings in some pretty cool new stuff.
They already announced a 2nd season so I guess this show has a pretty bright future ahead of it.
I saw it this morning and didn't expect it to be so short (didn't checked how many episodes there was) but overall it's pretty good. The character development isn't rushed neither forced on you. I liked the first episode with the introduction of Dracula being a total badass
