I really enjoyed this film. Real paradise lost when naïve Westerners stumble into what is really the Third World - a country run on drugs.
OK so it's a fictional representation, and so I have no idea how much of any of this is true.
In common with many other novels/films from Citizen Kane to The Last King of Scotland uses the device of an ordinary bloke who just happens to find himself meeting then working for a powerful wealth man monster.
It reminds me a bit of Breaking Bad or The Interpreter - and as all drugs movies are, this is very violent at times and tense.
The ending surprised me and I hated the very end though no spoilers here. I could have done with some text about what happened to Escobar and the real people featured at the end too.
