Really? I thought the emotional hooks were fine. If you got tired of them after only 13 episodes... D:! I'm sure they would have told the story differently if there was more episodes, though.
I'm not sure about the extra Fear, or about Pity. Maybe another hook while Nyu was around? Also, towards the end, things changed quite a bit, didn't they?
Which parts made the show's emotion or action grow a bit dull or repetitive for you, GW?
