Well, once I went and actually read the thing (instead of going off like a candy assed baboon based on spoilers) i did enjoy it. A lot. A lot of new story possibilities open in the DCU. A more nuanced, real life attitiude is there, if you can say such a thing in a world of flying men with capes.
It still stands as probably the best miniseries of the year. Tight, interesting writing, and terrific artwork, actually accomplishing some story points instead of Armageddon 2001'ing itself.
I'm not crazy about the idea that this is just a prelude to a prequel to a miniseries that will REALLY shake things up. Let's tell a story all by itself instead of setting up the next 2 freaking years, hokay?
