I loved the first few seasons, but around the time that Negan came, it went downhill. The main thing I liked about the show was the emphasis on humans vs walkers. But now it's mainly humans vs humans.
I feel like the show got sidetracked, and there are so many unexplored avenues. e.g. I would be interested to see if they could connect with people overseas. If they can build things up again and create new towns etc. And gradually restore humanity etc.
