I know people were complaining (as always) about all of the mini-series, but DC did a good job of putting out enough different stuff for everyone. Deadman and the Flying Graysons didn't interest me, but I'm glad to hear you liked it. Some of the minis are quite good, while others seem like DC used whoever wasn't working on the reboot to throw something together.
In a way, though, I wish DC went full-on Age of Apocalypse, cancelling their main titles before Flashpoint and having only the minis and the main series going on for the summer (yes, AoA only affected the X-titles, but I meant that the X-titles were put on hiatus while it ran its course). I would have picked up more of the minis that way and they could have used more of their talent stable this way.
Oh, well.
