People keep moaning about repeating story lines, but there are always gonna be similarities between them it's what "the world" is like now for them, also if nothing kicked off and they just stayed in the safe haven for a few seasons then you lot would complain that it is boring and like season 2 where everyone moaned about the farm, so just because there are similar story lines it doesn't mean the show isn't good just take it for what it is it's got at least another 3 or 4 seasons in it yet, I reckon it will eventually finish with them ending up in Washington and then getting and air lift to an island community somewhere or something along those lines.
The thing that keeps it interesting in my opinion is how the characters have all developed, remember when people used to accuse Rick of being soft and a poor leader, look at him now "if they can't make it work, then we will just take it from them" he is completely ruthless and isn't afraid to make the tough calls while still being morally correct, even Carl who used to be a massive liability can easily handle himself these days, Daryl off course is a mother****in G, I can see him struggling to fit in with this new group, I just hope none of the group abandon him and take the side of the politician women which I can see Michonne doing unfortunately as she seems desperate for a normal life.
I hope none of the older cast die anytime soon, if people have got to die please make it The Ginger guy, Eugene, Rosita or the pastor leave Rick, Daryl, Carl, Carol, Glenn and Maggie alone please the show needs to retain that link to the original group.
