I honestly think it starts going downhill after the pilot. In hindsight, even the best of the show wasn't all that good. I tapped out after Negan showed up. I didn't make it to Glenn's second death. By the time Negan showed up I was just exhausted with how repetitive the show was ending up.First few seasons are good. It goes down hill pretty quick like Dexter.
The pilot was outstanding though. One of the best ever imo.
