I highly recommend this to everyone who's even remotely interested in anime. The story is interesting, the characters are well-rounded, the animation is great, and the music is awesome; it's quite violent and bloody, too, so if that's not your mug of coffee, don't watch it. The sub is excellent while in dub, it's still good - in my opinion - , but season four will take some getting used to, especially if you're used to sub.
