I don't know if I saw the same movie as the rest of the people describing it as a master piece but I personally tried as hard as I could not to sleep. The movie can be divided into to parts . The first part can be thought as a documentary (and a low budget one) whereas the second one as an extremely bad sci-fi. Nothing made sense in the movie overall, so many messages that we were supposed to receive but i feel like most of the good reviewers are trying to extract so many things that are completely incoherent and do not come naturally from the film. My advise to you: if you have other options to spend your time rather than watch this movie, seriously go ahead with those ones.
