A Strong Finish
Since any comic book creator always has to ask himself "What happens next?" Not all of the storylines are tied up in this issue. Some even make up some questions to be answered later.
At the end of the day, we get a pretty good ending to the big event here. I actually think the scene where Jason Todd "died" was a scene with a Joker some years back. Of course we can assume Jason will make his return some time later, and I can see him becoming a better villain for Dick than he was for Bruce Wayne.
Of course the story was just an opening for the Dick as Batman books, which we now know are pretty successful. I think it is a natural progression, and now would not care if Bruce ever returned.
