Has Netflix done anything that comes close to the first and third greatest television shows of all time? No. They did Black Mirror, Stranger Things (hey: season 5 of The Wire was no great shakes either), BoJack, the Flanagan halloween miniserieses, Dark Crystal, and most recently Man on the Inside. Those are just the things I personally appreciate. They're holding their own with FX, which is not a small achievement.
Black mirror was a British show first. I don’t know the others except for Man on the Inside - I’m skeptical, but if it turns out to as good as The Good Place, it will be impressive for Netflix.
Saul, of course. Netflix commissioned most of Black Mirror. Man on the Inside is better than Good Place (and than any Only Murders season but the first).
