First off, I'll tell you that the first several minutes of the first episode will leave you jaw dropped from the intense gore scenes. I've never been that much of a fan towards "excessive blood animes" but this one sucked me in. The story is pretty decent though the series will leave several plot holes at the end (BUT i heard that it is covered in the manga). Visuals are very nice with some really nice background scenery at times. The music is another strong point of this anime which can leave you humming the anime's theme by the end of it all. My only complaint is that there are times where it seems too excessively corny and trivial (maybe it's just me). Overall, this is a MUST see to all anime fans, casual or hardcore watchers.
