The last episode I watched was the last episode of the season with the cliff-hanger where Jeffrey Dean Morgan was going to kill a couple of people with Lucille. I watched about two minutes of the first episode of the next season and turned it off, never to watch again.
The first five seasons were great television. Season Six in Alexandria started to drag. I gave up pretty much when you did, when Negan came into the picture.
I think the best part of the show is the premise, when the Zombie Apocalypse first takes place and the survivors have to learn to adapt to the new world. Once the routine sets in, it's hard to keep up the momentum and the show became predictable and repetitive.
