You can look at the way that "A" flashed back to the time immediately before the season premiere as Scott Gimple and Angela Kang shining a light on the year's big character arc for Rick, and that was a story for the season that pretty much had a beginning (Rick puts down his gun to become a farmer), a middle (the Governor's arrival forces Rick to reluctantly go back to fighting) and an end (more dire circumstances turns Rick into the man who could do what he did to Joe and his gang, and who can be that confident that he is going to mess up the folks from Terminus). But beyond that, this was a season that was all middle.
Maybe that's just Gimple trying to course correct for some failings the show may have had under Glen Mazzara, just as Mazzara had to spend the beginning of his tenure pivoting away from some of Frank Darabont's decisions, and maybe this means that next season — which in theory will be the first time the show will have the same showrunner for complete back-to-back seasons — will have more forward momentum. And as I've said a lot the last couple of months, the show did need some work done to shore up its foundation and make us care about what happens to anyone beyond Rick and maybe Carl and Michonne. Some of that worked, and some of it didn't, but the effort was admirable and probably necessary, even if it meant putting the larger story on hold for a while. (More ideally, a lot of the character work would have been done back on Hershel's farm, or earlier in the prison stay, but you can't have everything.)
...
Mainly, though, I'm hoping that now that Gimple has a full year under his belt, we can get an actual sustained stretch of "Walking Dead" goodness, rather than the fits and starts the show has worked in for pretty much all of its run. If it's the constant showrunner carousel causing that, things could get very interesting. If, on the other hand, it's just the nature of the material, then you have to be ready to keep taking the good with the bad.
