Narcos tells the story of Colombian drug lord Pablo Escobar, his allies and the men that hunt them down. So you get to see the events from the pov of both the good and bad guys.
Personally I'm too young to have followed the events live so while the series is mostly based on real events it still feels almost fictional just due to how insane some of the stuff thats going on is.
This is quite easily my favourite of recent shows.

I actually found Pablo likeable early on till he ended up becoming nothing short of a monster.
