I've been thinking about past runs on Bat titles and AFAIK there are not many runs that have both length and central themes / ideas (i.e. not just a collection of "random" stories by a writer who happens to stay at a title for a long time).
Of those I do know, my favorites are:
- Morrison's Batman / Batman and Robin / Batman Inc run - #1 by a wide margin
- Brubaker and Rucka's Gotham Central
- Chuck Dixon's Nightwing
* I think Snyder's Batman run is a good candidate for that list, but it needs a bit more "meat" (time) - perhaps if you add his Detective Comics run..
I'd love to get your input - both on notable runs on Bat titles in general, as well as your favorites.
