Great season, one of the best. I miss one or two of the characters who don't appear, but not as much as I thought I would.
First episode is rough going. It gets a lot easier after that. It felt quite detached for me for at least 5 episodes just because of the situation, but I'm still invested in the individual characters, and the new guards and new inmates are all pretty good, particularly Carol and Barbara.
Probably my favourite season since s3 tbh.
