Action, a lot more action. And a lot less psycho-babble conversations about how people feel.
I Second the above poar re No More Farmer Rick, but I also don't want to see Rick as a near psychothic Brute. I want to see the Rick that is strong enougn to do what it takes to survive, but is also a hero and not an animal.
NO more boring character development dialogue. Develop the characters through their actions and their stories. If you have to spell it out like the viewers are dense, it is lame and not interesting. Good acting and good story tells more about the characters than any lame "let's discuss it without bothering to worry about our present safety or theats behind the next tree" heart-to-hearts. The Carol-Lizze-Mika-Tyrese story was a fabulous example of how to tell an intense story without psychobabble.
More complex story lines like the Rick-Tyrese-Karen-David-Carol-Judith-Lizzie-Mika story of Season 4. It was marvelously complex, one of TWD's best story lines, so heart stopping and so well acted across the board with all actors. (The Shane-Lori-Rick-Carl story of S1/S2 was equally complex and compelling)
Somebody in the series to decide they want to fight back against the Zombie epidemic (even if they are a failure). I guess, as it is now set up, that would mean more action for Abraham Ford, Rosita and Eugene -- even though it is obvious that Eugene is a flake and not the real thing. Does it bug anybody other than me that the characters are not boiling mad at the walkers? Is there not an upcoming generation of youngsters that want to take them out and save the world?
The end of the everybody-out-there-is-a-bad-guy theme. If the story keeps on in the direction it is now going -- with humans killing humans -- all the characters and the rest of humanity will be extinct by the time Season 5 ends. Already, they are facing extinction as all the children, teens and tweens except Carl and Judith (and maybe the Morales family children) have been killed off. Unless Terminus has teens, tweens and children who can be rescued from their delusional Termite parents -- or Rick and his group find some other stable groups of people with families not led by mad men-- human beings are toast. That makes the survival story boring and nothing more than a well-acted Mad Max.
