This was a very solid Batman book. The art was good, the story compelling and true to the characters. It took some unexpected turns, particularly in the epilogue. All and all, a great read. There was an especially strong issue early on in the book that showed Batman and Bane's lives in parallel that made for a really powerful character piece. I was very impressed by it.
The biggest reason this is only getting 4 stars from me instead of 5 is an issue with denouement, specifically a distinct lack of it. Issues ended with explosive moments, but then it was difficult to string together what happened afterward. This was especially hard to follow with the end of this I Am Bane arc-- we have some great denouement with Batman, Gotham Girl, and Catwoman, but we don't know what ended up really happening with Bane, which left me a little frustrated as a reader.
