I really enjoyed it. I can understand some of the criticisms as far as it being slow, but I also think thats deliberate. It might have a slower pace, but I disagree with the criticisms that nothing happens. This isn't a show that's about the reveal, plot twist or mystery box around the corner. In fact, everything is pretty much known fairly early on in the series. It's not about surprises. Its more about the situation and how the characters respond to it. It's pacing is deliberate, and it might not be for everybody. That's fair, and I think people who start arguing that those who don't like it don't "get it" are being pretentious douches.
Not every show needs to be about mysterious plot twists. I dont necessarily want every show on TV to have the same pacing as this one, but Im super glad theres at least one doing it this way. This kind of storytelling has become sort of lost over recent years in favor of more "bang for your time". Im all in for season 2.
