This is by FAR the greatest movie ever made. Not because of its story (which is perfect and required deep thought for it to make sense), but because it ACCURATELY predicted Mankind's future. Everything in that movie that was once science fiction over 50 years ago has been created (iPad, Space Tourism, video conferencing, Robotics in space, etc.) An everything in it that has not since been created for use is currently in the experimental stages (suspended animation). That is why I love this movie, its almost like Stanley Kubrick was a time traveler of sorts lol.
