Can't remember if it was you that we suggested True Detective to a few weeks back, nice self contained seasons.
Horror wise, Haunting Of Hill House is some of the best written horror i've seen in movie or TV form for years and years.
Sci fi - i'll echo Love, Death and Robots mentioned above, a few dire episodes but some stellar episodes too, all short stories. Also Altered Carbon season 1 is great viewing.
I enjoyed haunting of hill house, the "sequel" starts very soon - haunting of bly manor
