For the show to take a risk and do something outside the box rather than the same formula every season of:
The group ends up in a new setting
Rick tells everyone how "they can start a life here"
Rick vows to just blend in
Something happens that causes tension with the group and their new hosts
Rick takes over
Something bad happens that sets up a big battle
In the battle, the camp is destroyed and eventually overrun by walkers
Our group ends up on the run, wandering aimlessly (potentially for a half season)
Back to step 1 and repeat
Say what you will about LOST, but they were willing to take risks and change the show so it wasn't six years of just trying to get off the island for the first time
