Another vote for Stranger Things - although it is essentially just a bunch of different source materials merged in to one show - brilliantly cast. Not that the writers have claimed any different.

I'm enjoying Silicon Valley, but that's prob because I work in tech and there are lot of character archetypes in there I come across on a daily basis.

Similar vein 'Halt and Catch Fire' is really good based around the time of the birth of the PC (and loosely based on Compaq in Houston).

For throw away fun / guilty pleasures i do like Ballers.
