I know someone who claims to have quit watching TWD multiple times. I just don't see what pulls people back.
As for me, once they started the season after they moved into the abandoned prison, I was done. I could see that it was just going to be the same thing over and over again in a new location.
I honestly sat on all season 9 for probably 2 months on my DVR because the show IMO should have ended after they took down Negan (And I didn't want to see more "find another place to live" bullshyt.), but season 9 has been pretty good to me and they're all now settled into their communities. Nothing like early Negan or the Governor though.
