When Morrison is mocking the conventions of comics in a meta-way (as he does here with a replay of the phone gimmick that killed Jason in the first place) I really enjoy him. Of course, he has to make sense as well (my problem with Final Crisis) but still...
Also I liked the white stripe in Jason's hair if only to serve as a reminder that he was dunked by Talia in the Lazarus Pit and could serve (even any writer want to bother) as an explanation for his violent nutso behavior. Talia herself was killed and put in the Lazarus Pit over and over again by Nyssa which could explain why she is being written now as pure evil.
