Holy shit. Gotta say, even though this is almost certainly a mini-series and will have no other seasons, it's one of the best shows I've ever seen on TV. Not sure how popular it is mainstream yet, but the production value, acting, plot and everything make the show so epic.
I recall following the story in the news back in 2015 but my sister knew nothing about it. Watching the show gets you right inside the mind of the prisoners and the people around them.
The finale (episode 7) aired last night and was 1.5 hours long and finished it off very nicely. I highly recommend this show to anyone.
