Although the stories presented in Batman #0 work fine independently (even if the writing seems to be hand-holding the audience far more than necessary) the timeline makes absolutely no sense. In the first story, set six years prior to the present New 52 DCU, we see Bruce Wayne‘s early days after his travels working on becoming a vigilante before becoming Batman. And that’s only the beginning.
The back-up story jumps one year in the future and gives us the all three Robins (Dick Grayson, Jason Todd, and Tim Drake) in the early days of Batman before the Dark Knight had chosen a partner. Not only does the tale suggest all three are roughly the same age (an enormous change in Batman continuity) but it presents Jason, who is an accomplice to murder, as the most likable and least brash of the trio.
To tie the two stories together we get a Red Hood Gang which feels more than a little trite and appearances by Jim Gordon. The second story also gives us the origin of the Bat-Signal and the first glimmer of Batgirl.
For a comic that ties all these threads together Batman #0 should feel more than a mixed success (at best), but too many of these pieces don’t fit together and the overall narrative feels far too forced. Hit-and-Miss.
