Finally got around to finishing and it's a pretty weak, although not terrible, show. I agree with a lot of what Mr. B Natural and Trent Strong already noted: the drama feels forced, the writing is flat, and the characters are all generally pretty unlikeable. It makes for a pretty uninteresting show.
The 'every sentence is a story' gimmick comes and goes, and acts more as a brief, expositional backdrop than anything substantive for any of the characters. There really isn't any sense of real danger of threat during the entire show, in part because the entire guard staff up and down the chain are presented as utter goofballs. That sort of guts the show of any real dramatic weight, while the comedy is middling. It makes the entire thing feels modestly more serious than Kevin Arnold's high school. The ending also seemed to feel like a rush to some dramatic cliffhanger, with a few characters seemingly stepping a bit out of character; I'm sure it'll be effortlessly ignored in the subsequent season.
There are a few good bits in there -- mostly in the way of performances by the Taystee, Poussey, and co. -- but there just isn't a lot here that compels me to keep watching.
