This season was definitely the best in a long time, but I do think it's time to end the show. 10 Seasons is enough. Next season is Michonne's last season, and assuming Maggie never comes back, they're running out of characters people care about. Ratings are at an all time low and they'll just continue to get lower once Michonne leaves, so I think it's time to start thinking about the endgame. They're starting to catch up to the comics pretty quickly, and I think they could write the upcoming story arc into a fitting finale.
If they continue to follow the comics closely, this is my prediction for S10
A timeskip of a few months to get through winter. As cool as it was to see snow, I think it's a one time thing. The first half of the season is the continuing Whisperer conflict. Eugene or Ezekiel or somebody stays in contact with the person on the Radio. Negan goes off and kills Alpha to gain Michonne's trust. Daryl takes Dwight's role from the comics as the leader of the militia. Gabriel and a few other characters die in the war. Beta unleashes the giant herd on Alexandria. Michonne gets bit, taking Andrea's death from the comics. The herd is dealt with. Negan decides to go off alone and leave the DC area, and his fate is left open ended. Daryl and a group are sent off to meet up with the people from the Radio. Judith joins the group, and they travel to Ohio to the Commonwealth. Rick and Maggie are there, and idk they all live happily ever after.
