If they do something with that, it would be good. I just don't know that they will. I think the upside for Eugene's story is pretty good.
I would also say that I think shows like Breaking Bad, True Detective, etc. have lead to unreasonably high expectations for me, especially since Sunday night TV is pretty good right now. TWD is kind of an afterthought. Take Shameless, for instance. Every character is somewhat repetitive but within that I think they do a good job of still making the characters grow even though they keep doing the same ****.
Like I said, I'm not going to stop watching but it's mostly because I want to see how it ends at this point. I hope I'm proven wrong but I can't really think of a show that kind of flattened out and then was brought back from the dead, so to speak.
