Spoilers, of course.
In my opinion, this whole multiverse thing is being handled rather sloppily. The Monitor's stories seem kind of ham-fisted, and the writer's just kind of jumped right into multiverse-based stories too soon.
Jimmy's story is boring me, and his Elastic Lad thing against the Croc in this last issue didn't help.
The only things that are actually intriguing me are Jason Todd's new face-turn, and what they're going to do with Rayner.
