Even though everyone says that it is only suitable for "kodomo", what can I expect? Shows like K-On! and most moe/fanservice shows are listed as "seinen" and I think those shows are for the teenagers.

I say let it develop first. Apply the 3-5 episode decision. If it is good by the 5th, allow it. If it still sucks by then, treat it like most Gonzo shows: Burn it, then piss on its ashes, then burn it again.

Besides, if you don't like your American super hero anime, just go watch Batman the Animated Series again. Finding out that Sunrise animated some of the episodes in there= MIND BLOWN.
