A Space Odyssey

In Stanley Kubrick's 2001: A Space Odyssey, a mysterious monolith is discovered on the moon, and a manned mission is dispatched to discover where it came from. But along the way, the spacecraft's supposedly infallible HAL 9000 computer goes through something akin to a nervous breakdown. To my mind, this science-fiction classic is visually stunning, brilliant, and enigmatic with an ending that is both baffling and sublime.
