Quite simply, Togainu no Chi is the kind of awful show that you just keep on watching. The animation is awful, the direction is sloppy, and the whole thing is just kind of trashy. It also takes itself way too seriously. And, yet, I love it. It's just so bad it's good.
My only real criticism, since all my other criticisms are really just part of why I love this piece of crap, is that the BL is really light. But, hey, maybe it'll get better in that regard.
