The Walking Dead: The Television Series

[Vampyr]

I don't think the farm is the problem, people just perceive the static location as a cause for the stagnant plot.

It isn't. Going back to a Joss Whedon example, the first 3 seasons of Buffy took place in mostly the same locations, primarily the library at the high school. That one room housed so many scenes from each episode, and it never felt dull. They kept finding new camera angles to use, and the dialogue was always perfect.

Leaving the farm and taking the show on the road wouldn't fix anything.
