I'm one of the people who also consider it one of my personal favorites, if not favorite show ever. Season 2 is my favorite season of TV so far.
I think I've found difficulty recommending it to people because a lot of people aren't down to dwell in darkness for extended periods of time. It will make you live around those feelings of despair and explore them a bit, but I found the payoff to be amazing. You gotta be willing to think about the story, there's no "answer" if that's what you're looking for.
Oh, on TOS I posted some photos of happily stumbling upon them filming Season 3 in the middle of Lockhart. Awesome story/day. A friend and I made a day trip from Austin, doing the rounds, drinking beer and eating at a picnic table outside of Black's and wondering what the hell kind of festival is going on in downtown Lockhart. There's a bunch of camping tents out in the middle of the square, all on the street. Then I start to notice a bunch of hippie-looking people walking around the square. Which is when I noticed something else is up, because Lockhart doesn't strike me as the type of town where hippies would be invited to have a festival. So we wander over to the square and it took me a few minutes before I realized we're on the fucking set of what became the first episodes of Season 3. Theroux was in his Police uni across the street, and Carrie Coon's fine ass was walking with an assistant within arm's reach, right past me. Eventually somebody realized two Mexican bros looked out of place as fuck on the set and they shooed us off. The big floating Gary Busey was up at this point (and the man on the tower). Pretty cool.
