Yeah, I think that might have worked better in Kimikiss format. But I think the main problem was that the popularity of the game exceeded the quality of the stories.

EDIT:

I was worried that I wasn't going to be liking Haibane Renmei that much but I've liked the later part of the series much more than the earlier part. Episode six was the turning point for me, but I really started to like it more after episode eight or so. I'm up to episode ten now. I'm looking forward to seeing how it turns out.
