Best season IMO.
Pablo stuff was entertaining but like @JamilALAmin said, the story line was much deeper here. Obviously things weren't the same as they are in real life but I feel like the show runners did get things as close as you could get. The Jorge storyline with his real-life consultancy on the show was also great. Pedro Pascual is a much better lead and better at being a peice of shyt than the Murphy narration.
The gentlemen of Cali and their depictions especially Gilberto is spot on with what I've read about them.
Oh and props to them for keeping the main theme and the opening is superb
They should of had a couple more episodes to show the end of chepo and pacho. I felt cheated at the end, build those fukers up and have their deaths during some monologue
