Also loved they pulled everyone in the Batfamily into things even if it was just a bunch of cameos. Joker in the precinct creeped me the hell out.

But I was reading in a blacked-out room with TDK Rises music in the background. Him going after Barbara and Jim is an interesting and not totally unexpected twist, but I felt really scared for Gordon. Especially after him in the elevator... "Can you tell?"
Batman being a dunce is the only downside of the issue. Seriously, he couldn't avoid a giant hammer? Plus he did the shonen dumbass thing of "no one else take him, he's mine!" *proceeds to endanger tons of lives because of selfish pride*
Will be interesting to see how Damian's arrogance plays into things, he hasn't really been knocked down a peg, then again he did beat Joker to a pulp last time they faced off.
Also, guess it's confirmed, Joker knows Bruce is Batman. Knock knock, Alfred!
