Batman #9 - 13 - "I Am Suicide" - was a significant improvement over the previous story arc. Much closer to the Batman I like (the master planner who is always a step ahead of you) than super action hero Batman. Janin's a great artist too, displaying some fantastic storytelling skills throughout the arc.
The Catwoman murder spree seems a little out of character, but it works in context. The infamous suicide attempt also seems like a logical addition to the lore.
In fact, the only thing I didn't like was #10, and Batman's initial assault on Santa Prisca. The constant narrative repetition, the back breaking, Bruce "fixing" himself. It all stretched credability somewhat. Am I missing something? Was something more clever happening here?
