I love this movie, this is the very first time I've watched it, definitely sends chills down my spine, it makes you rethink of history and life itself, very thought provoking movie, it left me with many unanswered questions, I literally felt like asking questions to John, as they kept appearing in my mind while watching movie, really this movies is a good food for thought, but unfortunately it's underrated and must appear with movies like 2001: A Space Odyssey, a must watch movie, if you're curious about everything...
