See, for me, maybe the problem was in the execution, but not in the idea. Woodbury in the comics was basically anonymous aside from TG and a few characters. It was a wonderful idea to open it up and see WHY this community worked the way it did... HOW it would have gotten that way. Plus, this treatment adds shades of gray. In the comics (which tend to be morally simplistic), TG and Woodbury = bad and Rick/prison = good. I like that we're seeing ordinary, boring, pedestrian stuff in Woodbury. It shows it's not some sort of dark castle where only evil lurks.
I disagree entirely. Moral ambiguity is a central theme of the comic book series. Shades of gray are its specialty. Morally simplistic? If anything, the moral dilemmas featured in the comics are extremely watered down and streamlined on the television show. Woodbury doesn't equal bad in the comics, as you have put it. The Governor is bad, yes. However, it's explicitly stated that the Governor has fooled the citizens of Woodbury into believing that he's a good man with good intentions. In other words, the citizens of Woodbury, in the comics, are mostly normal people who would've never gone along with the Governor if they knew what kind of man he really was. In fact, the Governor is ultimately (comic spoilers to follow)
So, it's not quite a "dark castle where only evil lurks." Doc Stevens is certainly a good man (who happens to be faced with one of those "simplistic" moral dilemmas). He's also a developed character that is introduced to us organically; something that the TV show fails to do with its citizens of Woodbury characters. The dynamic between the Governor and his people in Woodbury is actually really similar to that of the TV show, only crafted in a much more compelling manner.
The TV show isn't attempting to answer the WHY or the HOW in regard to Woodbury. It's just giving us stilted scenes with nothing characters, for the express purpose of filling out the run-time. Personally speaking, I don't even find myself asking WHY or HOW. All we need to know is that the Governor fooled people into believing that he was a good man, which takes little time to explain. We don't need to know anything else in order for the plot to move forward. The TV show has a serious problem with moving the plot forward, however.
