Re: DC's New 52: Reviews and Discussion (Spoilers welcolme and likely)
I think he wore out his welcome on the Superman
titles, first. He was the last of the crew from Death of Superman
left and a big part of Superman Blue, for example.
I used to love his art, but then, like his writing I started liking it less. Especially when many of his characters could be interchangeable and he seems capable of only doing a few poses. Again, like his writing, his art became stale in the late 90's.
