The term "Full Morrison" means absolute, balls-to-the-wall, avante garde Morrison insanity. This is "Full Morrison." If you dislike that, if that makes you experience unpleasant emotions, if you only enjoy Morrison's accessible books, if you have trouble with alinear narratives, this is not the book for you. That being said, this is the wildest, most unique, ambitious, and entertaining Batman comic I've ever read. And the artwork, starring Yanick Paquette, Cameron Stewart, Frazer Irving, and Andy Kubert, is fantastic. So for that it gets 5 stars.
If you haven't read any of Morrison's Batman run, do not start here. You will bang your head against the wall trying to make sense. Go back to Batman and Son and start there. This comes between Batman Versus Robin and Batman Must Die in the Batman and Robin series and generally explains what happens to Bruce after Final Crisis. Again, if you haven't read Final Crisis and don't know Bruce's fate, stop reading right here.
So following Final Crisis, Bruce bounces around time like Scott Bakula in Quantum Leap. Although the places in time are essentially random, they're fascinating times for a masked vigilante, and events of importance take place which drive the plot. These events also resurface constantly throughout the book because this is a story where time travel goes wrong (although aren't they all?). Each chapter adds layers of mythology which slowly reveal the central mystery and its various details. What's in the Bat Box? Where or when is Bruce going? Will he ever get home? Why was he sent back in the first place? And then we learn how various characters fit into the Batman run through the time travel narrative, such as: The Black Glove, Doctor Hurt, John Mayhew, Thomas and Martha Wayne, Professor Carter Nichols, Darkseid, The Justice League, Red Robin, Batman and Robin, and Blackbeard, to name a few. If you have questions from Morrison's Batman run or Final Crisis, this book is like the Key of Solomon, telling you how to read his Batman run and conjure up its grim and fantastic magic.
Although I didn't understand all of the avante garde moments, and honestly I don't think we're supposed to, this is simply an entertaining read. Batman is not a man who often travels from Gotham, let alone time travels. And that's pretty risky on Morrison's part. But it pays off if you're willing to keep an open mind. Really open! Because most Bat books take place in Gotham on solid ground with familiar villains, and we're generally happy to read those books. But here we really have no idea and it’s the unfamiliarity and alienness that makes this so great.
