Love this. Gorged on most of both seasons in two days. Can't believe I didn't guess the twist at the end of season one, it was pretty guessable in retrospect, but I suppose watching them so quickly it didn't occur to me. Like a couple of others here, thought I'd guessed that the twist in season two would be that this was the Bad Place for Danson's character, but that was mentioned in the second or third episode as one of the ways the team had tried to defeat him, by convincing him this was the case, so seems unlikely that will be a twist now.
I'm on episode 8, Season 2 so had been avoiding this thread in case of spoilers, but haven't read anything that has given away what happens in the rest of the season, I don't think.
The show is like an episode of Black Mirror which is better and funnier. Recommending it to all and sundry.
