Black Mirror Season 4

(2017, Sci-Fi, 6 episodes, Violence, Adult content.  wikipedia )
This British near-future Sci-Fi series is very edgy. Each episode is a distinct story, like the old Twilight Zone TV show. I enjoyed it but my wife found it a bit intense.

Godless

(2017, Western, 7 episodes, Violence, Adult content.  wikipedia )
A hard boiled western, staring Jeff Bridges as the really, really bad guy, and Michelle Dockery (Mary from Downton Abbey) as a widowed ranch owner, just outside a town filled with only women (almost).
The initial situation seems insane, but is explained after a few episodes.  You can tell the good guy right away - his name is 'Goode'.   Something about the ranch reminded me of 'Riders of the Purple Sage', although the plot and situation is very different.

Alias Grace

(2017, Historical Drama, 6 episodes, Adult content. wikipedia)
A young servant woman in mid-1800s Ontario commits some sensational murders. This provides an interesting look at life, culture and attitudes in Canada in those times.

Ozark season 1

(2017, Crime Drama, 10 episodes, Adult content. wikipedia)
A brilliant financial adviser finds himself compelled by threat of death to move his family to the Ozarks and launder money for organized crime. The first episode is so over the top, I wondered what they could do to beat that for the rest of the season, but at times they did.

The Crown

(2016-2017, Historical Drama, 20 episodes. wikipedia)
This chronicles the lives and scandals of Queen Elisabeth II and the royal family. Sounds like a bunch of puffs arguing over which dress to wear, but they've made it interesting enough. So far, they've made it through the Profumo Affair, and more seasons should be on the way.

New York Times 100 Best Movies On Netflix

Finally, here is a 2017 list of the '100 Best Movies available on Netflix', which actually seems to only have around 50 movies listed, but this list is here: NYT 100 Best Netflix Movies.
There are a lot of movies I'd add, a bunch I'm not familiar with, and a few I'd remove (Meeks Cutoff, for instance), but at least it's some guidance.
I'd definitely agree with the following from the list: To Kill A Mockingbird, Jaws, Schindler's List, Jackie Brown, Boogie Nights, Full Metal Jacket, Zodiac, Gone Baby Gone, Memento, Spotlight, The Sixth Sense, Inside Man, The Godfather, The Shawshank Redemption, and others.
A pleasant surprise is the inclusion of Pee Wee's Big Adventure, one of my favorites!
