It's not supposed to make you think. It's art, it's not supposed to do anything.this is the stuff folks resort to when defending 2001. "sure it's boring, slow, and tedious, but it's supposed to make you think!"
If you're in the right frame of mind, though, it can show you things that you've never seen before, evoke deep and powerful emotions, resonate with you long after you've seen it and make your life a little brighter and more interesting. But no, 2001 is not a very entertaining movie, there are no thrills, no belly laughs and no instant gratification for the audience.
Surely there is a place for all kinds of films, though, right? And I'm sure you'd agree that there are movies that can't be adequately apprehended by simply using the boring/cool axis. Sometimes things are a little more complicated than that, and a little more rewarding.
This. Very well said.
