The "philosophy" in this movie is about as deep as the first 3 pages of a high school text book. The whole movie is nonsense. It's like the writers took a whole bunch of random plot points and character notes, put them on index cards, threw them on the floor, and went with however they landed as the script.
This movie basically exists to show off barely clothed young actors. The only saving grace to this one is the great architecture of the bunker and the beautiful shooting locations.
