Treme didn't keep my attention for some reason...I went in thinking I'd love it and yet, two tries and I stopped about the same time, towards the end of S1.
Loved Succession after thinking I'd dislike it.
Band of Brothers is A+ and Fargo I've enjoyed each season, but S1 was hard to top....fantastic.
Justified I really liked for a few seasons, I just wore out and didn't finish it.
Battlestar was good, but I don't think I finished it. I'm seeing a trend here.
Oooh, Mindhunter - I keep forgetting about that one. That or The Americans might be next.
And awhile back I think you recommended a German period piece type show, subtitled...I'd have to go back in the thread for that.
