Never really been on Netflix, 'cause I pirate all my shit. Here are some series you should look up though;
Godless
Game of Thrones(obviously)
Vikings
Peaky Blinders
The Sopranos
Taboo
Narcos
The Last Kingdom
Hell on Wheels
Banshee
A bunch of other ones, I can't name at the moment. (except for the other obvious ones being The Walking Dead, The Fear of the Walking Dead & Breaking Bad).
Just watched "La Casa De Papel" so good I swear, it's about some massive robbery when they seize a building and print off money for several days, I wont spoil it for anyone who is going to watch it but I suggest everyone does because it's one to remember. :)
I feel like I'm the only one who liked that Taylor Lautner movie where he did parkour... What is it called? ... Tracers! Does anyone else fuck with it?
