I started watching this series at the recommendation of a friend who tends to disagree with me entirely on what constitutes a great show. On this one, though, we totally agreed. I'm surprised it's not terribly well-known, because for a "premium channel" series, it's very well done. And the writer had the common sense to go for 4 seasons, then "get out" before the concept gets old, which was quite wise, IMO. At any rate, I almost never purchase movies or "TV on DVD," because I almost never rewatch them, but this series I've purchased every single season & have watched them twice now. It seems like everything is somehow worked into the plotlines (Amish, Indian reservations, White Supremacists, cops, hackers, women, etc.), but somehow, it manages to all work together quite nicely. If you're looking for an edgy but interesting show, this is it!
