Stranger Things and the Marvel Hell's Kitchen series (Daredevil, Jessica Jones, and Luke Cage so far) should appeal to most of the nerd crowd and have a lot of mainstream popularity too. I also enjoyed Marco Polo, Sense 8, and The Get Down personally.
It's sad they couldn't license any real super heroes. Those guys are lame.
House of Cards started it all highly recommend watching it if you have not.
Chewing Gum is a recent favorite of mine.
Black Mirror and BoJack Horseman is the only Netflix original content that I think is phenomenal. The other stuff is fine to mediocre.
