Anyone with enough of an attention span to follow a story that they haven't seen 100 variations of a thousand times will love this show. Every episode has a twist that is, for all intents and purposes, impossible to predict. To me, that means the story is enjoyable, because the unexpected is kind of my thing. The opening and ending songs were good enough that I never skipped them, partially because of animated sequence at the end. I hate to say how many anime I've dropped this winter because I'm so tired of the same 'ol same 'ol. That made me put this near thetop of my list of favorite anime ever, along with Monster, Gankutsuou, Full Metal Alchemist, Mononoke Hime, and a few others.
So if you're looking for another OP MC and his Hottie Harem at the beach between progressively challenging boss fights, this is not for you.
Otherwise, get past the idea that everything in the art form has to repeat what's already been done and watch something different for a change.
I recommend the Fire Hunter to any art lovers out there.
