In my eyes, The Americans is the best show currently on TV, edging out Game Of Thrones and Better Call Saul.
I really want to love The Man In The High Castle but agree with whomever said the lead characters are wooden. Same with Westworld, although the acting is much better.
Old shows:
The Shield (the first TV series that made me sit up and realize TV was pumping out better stuff than Hollywood).
The Wire
Mad Men
Deadwood
