I'll have to check out some of the series you and others are mentioning. Like you, I watch too much TV, but part of that is because it's gotten so much better in the last decade. I don't feel like I'm (entirely) wasting my time anymore.
I agree, "Longmire" was pretty good. There was only one season on Netflix, so I hope there is more. My only gripe was that between Walt Longmire and the Lou Diamond Philips character, there was an awful lot of "strong, silent type" stuff going on. I guess that's part of the Western mystique, though.
I keep hearing good things about "House of Cards," but it's hard for me to get into political dramas. I'll have to give it a shot, though.
