I'm just ready for the show to go back to being about a zombie threat, not always the humans vs. humans angle. It's almost as if the zombies/walkers are just a sidebar story line, just a nuisance compared to "next big bad guy" plot that several on this thread mentioned. I agree it's repetitive and tiresome at this point.
I know it probably won't go this way, but it'd be nice to finally see large groups band together to try and take back a city--refit one of the earth movers that piled all of those logs on the road into some zombie-smashing machine and take back some communities. Then, try to somehow re-establish communication with other parts of the world, and SOMEDAY actually explain why it happened. Pipe dream, I suppose...
