Hahaha, yea, there're a lot of things wrong with that show's setting, sadly. It looks promising at first, but my interest slowly diminish with each episode.
I give anime a chance, at least until episode 5 (or more/less, depending on some situation) before I decided whether I should stay with the series or show it the way out. Personally, if I've to choose, I'd rather become weak than wasting my time on shows that failed to entertain me when I could invest it on some more rewarding things. The downside is I could only bitch on the portion that I've seen, so if it actually manages to get itself better on a few final episodes later, well, uhh, it doesn't change the fact that I found those other episodes to be terrible, so I can still bitch on that, yay!
