Still haven't read this comic so have no idea what's going on, but my reactions are:
Is Dick driving on the right?
"This time it's personal" was not made cool again. Ouch.
Now even Dick's referring to Bruce as "your Dad" to Damian? I know this comic likes to remind us that Damian is Bruce's son and Bruce is Damian's father as often as possible, but one son doesn't usually refer to a shared parent as "your dad" to another. Seems like it's trying to remind me that Dick doesn't count as Bruce's son in this book.
Quitely's art grows on me. Sometimes I'm put off by the mushy, cottage cheesy feel (probably the wrong description) but I do love the movement and the way he spreads things out over the panels. Especially when they leap down together. And also the panel where he throws the antidote. It's exciting to look at.
I still like the villains. As I think someone else said, this is a real refreshing change from the noir overload. I don't mind the flying batmobile. I'm interesting in reading the rest.
