I can't see why people would think this show is bad at all. It's animated by the same studio that did Death Note, it's incredibly unique, and it's fun to watch. The manga volumes I have read are incredibly random, but incredibly entertaining and genius, and although the Anime is quite dumbed down and rearranged, there have been no fillers; Although the story has been changed quite a bit. The show has sadly been one of the series to not be subbed regularly, I was glad when catchphrase picked it up and they did it well, but then they slowed down. Now I'm watching Ainex's releases and theydo a really good job, like they do with Persona -Trinity Soul- and how they did with Night Wizard. They are usually the first one out and have good visual quality and subbing accuracy.

I would recommend anybody who likes Anime to at least try this series, I know I usually overrate what I watch, but this series definitely deserves a 9.
