Ok... so I might be the only one that feels this way... but that episode... might have been top 5, Maybe even top 3 episodes of the entire series for me. It was one of the most grounded, realistic episodes. Having friends battling cancer currently it hit close to home. And just damn.... that was really good... the worst part was the very end, I really hate Maggie now and the fact she was only brought back because she failed at her other show. Everything minus the very end was nails! I might be biased because I've always really liked the character of Negan, but that back story was just perfect to me.
So all the extra episodes we get... Aaron/Gabriel episode was good... and to me, the Negan episode was amazing. The rest were just completely trash. Another good thing about this Negan episode is I feel like there was never a time and place to have this episode in any season since we first met Negan, it always would have felt out of place to have a whole episode related to his backstory.
