Just working my way through Stranger Things now, gone through 3 episodes this evening.
Other series I've been into/caught up on:
Gomorrah
Making a Murderer
House of Cards
Peaky Blinders
Line of Duty
Luther
Better Call Saul
Netflix is thoroughly recommended btw, given the free trial and easy cancellation policy, it's a no-brainer IMO.
Another for Stranger Things. I love the whole 80's feel of it. Unfortunately, I read a spoiler on Facebook...
