Isn't this plot kind of the same as Morrison's RIP/ROBW? Conspiracy against the waynes thourhout the years, enemies he was not aware of, trying to drive batman crazy, etc.
It's a variation on a similar theme. It's not as if Morrison invented the giant conspiracy angle, or the idea of multiple enemies trying to push a hero past breaking point. He just threw the elements together in a distinctive and entertaining way.
Synder's work with Batman (in this book and in his previous runs on Detective/Gates of Gotham) has been pretty enjoyable so far, and it definitely seems to be building towards something big. Didn't he talk a while back about his third arc being the real "game-changer" for the book? Maybe that's where we'll see everything come together.
This story line reminds me of Frank Miller's run on DareDevil. Miller introduced The Hand and that story line ran for a while and became part of The Marvel Universe. Snyder reminds me of Miller's style and I can see The Talons becoming part of Batman's lore and part of DC.
