They're not going to do Griselda Blanco?
TBH, in the grand scheme of things, she really wasn't that big of a player in that time period. Americans are familiar of her from those Cocaine Cowboys fantasy movies and what went down in Miami. She wasn't one of the partners of Medellin Cartel (Ochoas/Escobars/Lehder/Berna) or Cali Cartel (Rodriguez Orejuela brothers/Pacho/Chepe). She answered to them. As crazy as it sounds, and no disrespect intended, by no means was she at the level of those dudes.
I've said this before, but if anyone wants to get a much more authentic picture of the Medellin Cartel, watch Pablo Escobar, El Patron del Mal on Netflix. It's like 70+ episodes, done entirely by Colombians in Spanish with English-subtitles. They have no interest in glorifying him nor what really occurred back then, nor exaggering the USA's role in any way. They have a lot of original footage from some of the events of that time. It's not Narco's glossy, but it's gritty, reflecting that time period. You won't see any Americans running around alone in the poor barrios of Medellin or downtown Bogota slapping up taxi drivers.
If Netflix were to continue in Colombia, what came next was a massacre worse than Pablo's reign between the paracos (Los Pepes became AUC), FARC, and the government. Some truly nasty and brutal campaigns for control of the drug markets (crops, properties, ports, international markets) were waged from late 1990s to early 2000s. The gloves most definitely came off during that time. The AUC gave Los Zetas the playbook to run with.
Narcos Mexico showed how Mexico got into the game and who the top dogs were and will be. Miguel Angel Felix Gallardo, Rafa Quintero and Don Neto were the first Mexican cartel and responsible for how the game is now played. Of course, they deserved their season, which sets up for some interesting seasons to come. El Chapo, Los Zetas, and Arellano Felix brothers seasons will ratchet up the fukkery that occurred in the 1990s-2000s. Sandra Avila Beltran will probably be introduced in one of those seasons, as she bridged Colombia and Mexico in the late 1990s-early 2000s. Plenty of stories to tell there.
