Watched it for the sake of the shounen ai but found there was almost nothing about it, on the other hand the art, visual language and animation of the episode were jaw dropping! This weird 30 minutes of an episode is a trippy action packed dramatic almost nonsensical hard to understand journey that does little in trying to explain itself. Sometimes it bores, other times it grips you hard to the screen. I'd recommend trying to watch the first scene and to chose from that if it interests you to complete the viewing, the fan-service driven promotional poster certainly doesn't do that piece of enigmajustice.
