I like some things that Bendis writes but him on a Superman title....I respectfully say, please do not do that DC!! I actually like the current Superman and Action Comics title.
When it comes to big name titles Bendis is a hit or a miss. Ultimate Spider-Man Hit or Miss most issues. Avengers Hit or Miss most issues. Jessica Jones Hit, Daredevil Hit, X-Men complete MIss.
Superman is a optimistic character that is supposed to inspire ppl to be better that does not mesh well with Bendis' cynicism, and dark Brooding nature. I can see Bendis on either a Batman Book (Lord Knows DC is not opposed to yet another Batman Book, *insert eye roll here*)
Or a Birds of Prey book, Green Arrow, or maybe they might try to make him bring up another character, like: The Question, or Dr. Fate, or maybe Batwoman. Bendis works well with single focused Characters, with a limited cast, his Jessica Jones, Daredevil and Moon Knight runs are my absolute favorites. All of them dark and brooding characters that were put through the wringer and now have been brought to the limelight of mainstream pop culture. Team Books are not his thing his thing so please no Justice League, or Teen Titans.
And Please Please No Superman for him.
I hope he's recovering well though.
