Best Batman-related issue I've read in a long, long time. Hell, it's ironically my favorite since Morrison wrapped up Batman Incorporated. It didn't lay everything out in stark black and white terms, but it definitely did its job reconciling "Barbathos" in Dark Knight, Dark City, Morrison's Barbatos the Hyper-Adapter, and Snyder's Barbatos the Dark Multiverse god.
If I'm not mistaken: When the Hyper-Adapter was attached to Batman in Final Crisis #6, that's when Barbatos first "saw" Bruce from the Dark Multiverse. Barbatos gained a foothold in our universe through the Hyper-Adapter, and, when it took the bat visage in Return of Bruce Wayne #6, that was actually Barbatos possessing it before it got sent hurtling back through time. So when Dr. Hurt in the 1700's "saw" Barbatos, it was Barbatos in the "body" of the Hyper-Adapter. The bat that flew through Bruce's window and inspired him to become Batman? Barbatos. The giant bat he killed at the dawn of time? Barbatos, or at least the Hyper-Adapter in his image.
I mean, it's a long walk just to retcon Barbatos as an actual character, but I'm willing to roll with it. I'm also glad to get some clarity on the Court of Owls and how they factor in to all of this, as I was erroneously under the impression that the Owls were actually a force of good to fight back against Barbatos. Funny how, combining both Morrison and Snyder's mega-arcs into one, it creates a decade-long Batman story that culminates here in Metal.
