Atlanta (S1). Flat out the best show I saw this year. Moving, odd and insightful. I wish we had more TV like this. So sorry we won't get Season 2 until 2018.
Happy Valley (S2). I will fight anyone who says Sarah Lancashire isn't the best in this dark British crime series. So good.
Better Things (S1). Another FX gem, also featuring a hyper talented creator/lead in Pamela Adlon.
Stranger Things (S1). I don't think it's so great, really, but the nostalgia + soundtrack + the kid actors really made it. Plus, I was one of those basement D&D players way back when.
The Exorcist (S1). I expected this to be trash, but go figure, it turned out to be quite good. Dark and nasty for a network show, and I loved the ties back into the ongoing mythology + the larger conspiracies. I hope we get a Season 2.
Search Party (S1). This was a surprise for me, being a TBS streaming thing, but I loved the mystery and the really pointed commentary on finding one's identity.
Rectify (S4). This wasn't the best season of Rectify, but it was damn powerful. I can't wait to see what Ray McKinnon does next.
edit to add in: The Girlfriend Experience (S1). Riley Keough gives a masterclass in opacity. The whole show swings from kinda hot to super disturbing and back again. Some terrific moments, and that last episode is quite the thing.
Honorable Mentions: Quarry (S1), Animal Kingdom (S1), Penny Dreadful (S3, sob).
Shows I still plan to watch: Better Call Saul (S2), The Expanse (S1), Fleabag (S1), Queen Sugar (S1), Lady Dynamite (S1), The Americans (S2-4).
Shows that I tried to like but didn't: Daredevil (S2), Luke Cage (S1) and The Crown (S1).
