I think the luster is gone from TWD now. I don't think they can do anything to get back where they where in Season 4-5.
Thinking of the endless touch bumming we have between Negan and Rick, one can think back to Season 3 and the War against the Governor...it took until the 13th episode before Rick and the Governor actually met face to face...and I remember that being a huge moment in the series. After that, Rick didn't meet the Governor again until the the final Prison battle in Season 4 Episode 8. While the writers botched the Governor story as well, I look back at that plotline with a much more positive opinion after seeing how they've run with the Savior War angle.
