I would just like to say thanks for the last Osborn arc after Fear Itself, for giving us one more look at Norman Osborn.
But seeing as Bendis has had 7 years on Avengers, I'd just like to show my appreciation for making Spidey and Wolverine Avengers, things that have never been tried before. I'm not that fussed with the Ultron stuff because he hasn't been that big a villain I like. But I am grateful he killed off Janet the Wasp, (and thus allowed Hank Pym to be used in a most controversial manner by Slott), used Jessica Jones in Avengers,, saw the Infinity Gems used, and gave us the conclusion to the Sorcorer Supreme story.
I'm not sure I enjoyed Sentry's use and demise. Paul Jenkins created this character who was an enigma and Bendis explored that in Bendis' inimitable style, and made him into a train wreck. But then what could you do with Sentry? Look at Blue Marvel. Nobody has attempted to make anything of him, but Bendis made the effort with Sentry.
