There was a DS I?
Between the pics posted, the trailer, and the story summary, it just doesn't seem to mesh well to me. But, if they do a good job, perhaps all the discordant elements will in fact be the great advantage to this show.
Part of my seeming wishy-washy-ness over all the anime you post about Tatsujin, is that I don't want to set myself up to hate, or to love a show, before I have watched even at least one episode. But so far, I have always wanted to at least look at the shows you post. You have not brought forth any that repel me at first glance.
