Inspired by the name of an oil town in Texas, Sour Lake was the name given by Texaco in the sixties to a small town in the Ecuadorian jungle, known in Spanish as Lago Agrio. This name underlies the framework that builds the film: from the surroundings of this city to the Colombian Andes, where the jungle vegetation merges with the mountains.
Reviews
It's hard to see any effort in the film. There's no comedy to speak of, no real drama and, worst of all.
The movie runs out of plot and jokes well before the end of a two-hour running time, long for a light comedy.
The movie is wonderful and true, an act of love in all its contradictions and complexity
If you're interested in the topic at hand, you should just watch it and judge yourself because the reviews have gone very biased by people that didn't even watch it and just hate (or love) the creator. I liked it, it was well written, narrated, and directed and it was about a topic that interests me.
