Blackest Night is the DCU event you’ve been waiting for.
I just read Blackest Night #1, and since I don’t know if it will become hard to find I didn’t want to wait until my usual review to make this statement: This is the book that is the next (last?) chapter of the story of the DCU that started in Identity Crisis and continued through Infinite Crisis, 52, etc. I’ve long said that a lot of the disappointment in Final Crisis was that people were led to believe it was that chapter when it wasn’t. But it’s here now, so don’t hesitate to go out and get it if that’s what you’ve been waiting for.
