Plot: Take a walk through Jackie's mind - it's an odd place, to say the least.
The Darkness is cool. Darklings are funny no matter what anyone says and Jackie is a cool dude. That said, he's also almost up to Bruce Wayne/John Constantine level of bastardness but there you go.
Darkness has changed since the Batman/Darkness crossover. Occasionally crossovers have an effect on continuity, take Crisis on Infinite Earths for example. Most of the time, however, and especially pretty much all of the time when it is a cross company crossover, things stay the same.
Batman/Darkness has changed the whole premise of the Darkness forever. Where once we had a mob hit man with a quirk we now have someone looking for a bit of redemption and even considering taking the path of the hero.
This issue takes the whole idea of introspection to a new level with Jackie literally walking through his subconscious. While there is next to no recap scenes we manage to pick up huge amounts of information about our main character through the flow of things making this a good, if somewhat odd, hop-on issue. Not much Darkling action this time but we can't have everything.
As will be happening in Superman soon, the issues raised in this issue will force our hero to question his accepted origin story. This sort of thing keeps a character fresh but I'm not sure the Darkness was in need of it whilst it is so young.
All I want to know is - why a giant pink fluffy rabbit??
