7. Solaris
The 1960's and 1970's had a rash of sci-fi films that, up until 1977's Star Wars, were meditative, psychological thrillers. Evocative of the cocaine and acid-addled decade, most of these movies feature trippy, psychedelic sequences in which no one really knows what's going on or why. Well, no one unless you talk the arrogant know-it-alls that make watching these kinds of classics unappealing. It's no surprise that the guy who directed equally pretentious snooze-fests like The Mirror, Andrei Rublev, and Offret would craft a mind-bending, nay, mind-numbing movie. Solaris is the name of a planet whose body of water is presumed to be a thinking entity. And this body of water is a heck of a lot smarter than you, so good luck trying to understand the movie about it. Perception is reality in Andrei Tarkovsky's Solaris. He said it's about grief and loss, and I completely agree. Grief over losing valuable time otherwise spent playing stick ball.
