Just finished reading my copy in digital. I actually thought this whole issue flowed better than most of Lobdell's work. The Joker's labyrinthe is much more claustrophobic and personal than the one the Court of Owls put Batman in, and having the Joker operating it like his personal amusement ride gave it a nice flair of theatricality. I was really hoping that we'd get to see more of Tim in this issue, but hey, at leats at this point he's had the same number of panel appearances he had during Night of the Owls. The story really only dragged wheneve we checked in with Arsenal and Starfire, and I'm have the feeling that there section, and most likely the sections with the Titans, are going to be mostly filler while the Joker does his thing.
Jason's inner monologue and defiance of the Joker really sell the issue, partially because it poses an intriguing implication that I hope was intentional on Joker's part. Lobdell has stated that Joker's tale in RHATO was an example of a possible unreliable narrator, so each little twist of the dagger at Jason's personal history actually has two ways to be interpreted: either Joker really was Jason's sculptor and has controlled most of his life, or Batman was lying about the Joker not knowing the family's identities. It adds an interesting twist on these two controversial ideas by making them options for the same truth.
P.S. I can't be the only one who thinks the All-caste still seems a little underdeveloped and deus-ex-machina, am I?
