I really think that the Kodomo no Jikan entry should be handled with a bit more care. Anime News Network didn't go on some tirade to get Nymphet pulled. They were squicked out about the story, sure, as some people would, but since when have bad reviews or previews been the sole decision to cancel a release?

How is Firefly one of these at all? The premise is "the Wild West, IN SPACE". What's alienating about that?
