What missing in this story?
Yes, Grant Morrison is gone, but, that's not the answer I'm looking for. There is something literally missing in this issue.
Pros:
Paul Cornell, who is currently writing Knight and Squire, makes his first debut in Batman and Robin, and while his writing is very different from Grant Morrison, he still delivers a pretty twisted story especially at the end. Una Nemo, a former girlfriend of Bruce was recently killed, but the body was mysteriously dug up from her grave and returned. This all leads to Batman and Robin stopping a strange wedding. One aspect that's different from Cornell's writing is that he adds humor into the mix. Dick is joking around a little bit more while maintaining the cowl and Damian is...well Damian. I've been seeing Dick change a little bit lately since Bruce came back with other writers out there.
Cons:
The story starts off very slow. It's an unusual story, but the pacing is just off.
I don't know why, but the art just feels off. It looks decent and it should fit the kind of story that Cornell provides, but some pages just look odd.
Overall: Easy, but slow that's how I overall feel about Paul Cornell's writing right now. After Grant Morrison's run on Batman and Robin, I think it's well deserved. Now if we do something about the art, we might be in better business.
