I second pretty much everything you said. I get what he is going for, I just think the deconstruction in these cases feel much more excessive. It doesn't help we aren't really learning anything new yet about the character or thematic wise, its moreso about revisiting his fears and anxieties through these extreme examples. I'm hoping we do get some new revelations in regards to the character through this exploration, which I think may make all the reminiscing/torture worth it.
Wondering how much the Heroes In Crisis tie-in next is gonna impact the rest of the series. King has said HiC takes place between #54 and 55 (so before Nightwing got shot), so this will most likely be jumping back to that point in the timeline. Also looks like Gotham Girl is involved, so its probably connected in some way.
