The writing on the show has fallen off. I really like the comic story and some of the changes for the show are just silly.
The garbage people annoy me to no end. The stupid broken english and silly clothing just piss me off. Even in the comic I thought the kingdom was kind of cheesy. They do a better job of explaining Ezekial's front though.
The garbage people were pointless. I didnt give a flying fuck about them so the betrayal was just whatever, I saw that kind of coming. Rick had about zero reasons to trust them so it is stupid that he did. Plus like I already said he had no reason to believe they would even be useful. They said they weren't fighters, so how do you know it is even worth it? Just for numbers?
Someone mentioned that the garbage people and their leader specifically is someone from later in the comics. That may be the case, but it will be somewhat weird if they do that. It sort of makes sense, but then it also doesn't. I have a feeling though that they are trying to find new stories to fill time on the show. So we may be getting some back story on this particular character the comic doesn't have. I am not sure I like it, and they will need to step the writing WAY up to pull it off.
Next season will either put a fork in this series or it will become something different again. After the All Out War arc, the story changes in a pretty significant way. If they make the entire next season All Out War then it will be shitty, but the storyline after would be strange in the middle of a season. I am not sure what they are going to do, but the series gets increasingly more character driven. So if they don't start making that writing better it is going to be a sure fire failure.
