Rebirth in particular was really lacking in variety. As others have pointed out, even if you are determined to do almost exclusively superhero books, you can still do a variety of genres within the superhero umbrella. But with few exceptions we've gotten straight superhero. What drew me to DC originally, after being almost exclusively Marvel (except for Batman, of course) was (or is is "were"? I never know) books like Demon, Spectre and Hitman. They are doing a good job with Sandman Universe and Vertigo (lots of great stuff upcoming, it looks like) but I really would like more in-universe non-superhero (or superhero themed horror/suspense/war/etc) stuff.
