I was not aware of this documentary film. Not much hype if even any about it. All I am going to say, watch it! If you're not into this kind of adventourous film. Watch it for the first 15-20 minutes and decide if you want to continue, I definitely did! Probably one of the more intriguing film I've watched lately! Somewhat felt rush towards the end, I guess due to the duration of the film, but it is a must watch.
