Having said all of that, of the people I know who really follow the show on the creative/biz side are happy that the former show-runner was canned and replaced with Scott Gimple who wrote a lot of the best episodes.
Personally I'm taking a wait and see approach with the next season. If things aren't solidly turned around by the middle of the next season, I'm going to quit watching. I don't want to make the same mistake I did with Lost where I was so convinced they would fix the problems that presented themselves in later seasons that I stuck with it to the bitter end.
