Re: DC's New 52: Reviews and Discussion (Spoilers welcolme and likely)
A lot of what you see of the artist's work on the page was "ordered" by the writer. Sure, an artist might have some input, but it is mostly the writer's ball. So if Lee drew a lot of splash pages, it's because it was what Johns wrote and what he wanted to see.
Of course, I don't dispute that. in fact, in my op on this topic I called out Marvel's Bendis as being a big offender of this kind of de-compressed story-telling.
