Stanley Kubrick's 2001: A Space Odyssey is considered by many as one of the most beautiful and transcendent, if not flawless, films of all time. Deeply cerebral and photogenic, Kubrick's 1968 oeuvre is utterly mesmerizing on many levels. (If I say too much, I might spoil the film's beauty; so please check it out if you still haven't.)
One of my most favorite moments in 2001: A Space Odyssey is its ending, which is mindfuck at its most orgasmic. I've always thought that Kubrick's film is two films in one; you just have to watch it again right after your first viewing.
