I love this show, but in my opinion, this season, they have cluttered the landscape with too many characters.
TWD is Rick Grimes' story. It needs to focus on him and the relationships of those around him. I hope that Carl is an untouchable like Rick. The show could evolve to the the Carl Grimes story in time. Judith is merely a proper in the shows. However, killing off a baby is not going to happen.
There also some key characters that I want to see make it to the end with the Grimes family. I think Daryl and Michonne need to be standing until the end. Both characters have evolved into strong and important characters in the show. Both of them bring a bit of depth top the show, other than being walker killers.
The Glen and Maggie love story is losing it's luster. I always had trouble believing it in the first place. Maggie has lost her entire family now. One of the two or both could bite the dust to create a new angle. Either one alone would bring about a new direction in other character, that could be good for the show.
Carol's story has been told. She has come full circle from being an abused housewife to becoming a strong survivor. I'm not sure that you do much more with her character development in the show. She and Maggie have become the same type character sans the love interests.
Tyrese and Sasha's characters drive me crazy. Why are they even there? Put star trek red shirts on them and let them stay down on the planet, while the rest of the away team beam back aboard the Enterprise. Neither brings much of anything to the show. Sasha has become the village idiot in season 5. Tyrese might as well wear a dress. He has become the new "Dale"-the moral compass of team Grimes.
Abraham's character offers another bad as with leadership quality. He also has some range of emotional baggage going on. He is going to be on the show for another season or two at the least. He had Rick are going to be a team that hard to beat. His love interest, Rosita has not been developed deeply and could either be walker folder or could develop into a character similar to Maggie. Eugene, no longer serves and overt purpose on the show, He could end up providing the writers with a new direction if they can breathe some new life into his character.
Father Gabriel is dead weight. He could potentially serve as a moral compass but right now his character is not one anyone could trust for strength and guidance,
Morgan.... I don't think I have any idea how Morgan is going to come into play.
