Actually... Bruce Wayne having some kind of fetish-like thing for non-model kinds of beauty would explain how he could resist all the sex thrown at him from various DCU women. I think he and Waller having some weird sexual tension would have been amazing with the right writer, but it probably would have pissed off every reader more than "killing" him again.
I liked the Bruce Wayne made all the anti-superhero weapons angle from Kingdom Come better. He was all about knocking superpowers off the human evolution list.
