I’m on a roll with rock stuff, so I’ll just go with this.
I like the opening to Deadman Wonderland. In fact, I like it so much I want to watch the series. In my opinion, that’s when you know an anime theme is good.
Anyway, since I obviously haven’t seen the series, I can’t talk much about it. Except I do know of the plot, which is sort of a sci-fi/horror mashup about people who can control their own blood to be used as weapons, and is based in a prison/theme park where said people seem to gather. Which sounds awesome.
