I check in every once in awhile, but (like you said) it appears to be the same story line since "the Governor." And the spin-off shows are no different either.

It's pretty clear that the show's creators, writers, and network have chosen to cater to their hardcore fans (who love seeing the same thing over and over again) than to transition the storyline (to something new) or find an off-ramp to end the show (which probably should have occurred 3 seasons ago).
