I think it's okay. At least this way there won't be any sequel.
Matsuri is a likable character, friendly, mysterious, and her smile is memorable. There are things we never get to know about her, but I guess it's okay. I'll miss seeing her do and say new things.
As for Aono, I wasn't bothered by her Rei-like characterization. It's a pleasant and nostalgic experience. I can't make up my mind about her yet, I have to see 11-13. There should be more to her history, I hope.
