I think the show does a good job of not alienating huge chunks of people. Everything coming out of the entertainment industry has a political angle - and this show does too, but those on the right can enjoy the opposition to hippie environmentalism and the ridicule of all the Californians fleeing what they have created to get a respite in Montana. Beth's dressing down of the Northwestern professor was epic! Those on the left have conservation of land, Native American struggles, corporate greed and corruption, etc.
I'm someone that recoils at how dysfunctional each character is. The least disturbed person is perhaps Kayce or Monica, maybe Mo, but each of them have had their dysfunctional moments. There is no character that morally anchors the show. It's more a bunch of people who have a few things and people they care about and a few principles they live by, but they will do anything to anyone outside of that. It's an unrealistic but interesting story. It makes you root for some very flawed people to rise above, do the right thing, and be the hero - but they rarely do, and if they do, they are doing something horrible shortly. But, somehow, it works as entertainment.
The writers need to make sure they don't jump the shark and start to lose viewers. They have come close.
