First off, Hellsing is in no way for the innocent at heart. It has vampire nazis eating babies in one bit, and thats... thats pretty normal for the level of over-the-top-ultra-violence that this series gets up to. However, do I recommend the OV As
? ABSOLUTELY. The first one is essentially a retread of the first episodes of the TV series, but after that they go off and follow the manga. And it is ridiculous, glorious, hammy, violent, bloody, sexualized, and freaky as hell. I can't think of a favorite moment because there are too many good ones. The Japanese.... don't really understand Christianity, and this series will make you very happy that they don't, because their version of the church militant is freaking AWESOME. Also incredibly violent.
I can recommend it for anyone who is willing to give awesomeness a go, turn off their brain, and enjoy the logical insanity that this show is.
