I recently watched Dennis Hopper & Peter Fonda's 60s classic EASY RIDER because it was playing at my local theatre and it's just been pingponging around in my brain ever since. nothing it does is suuuuper innovative from the modern lens, but even still it's one of those movies that's just a pure shock of "Oh my god, you can do that?"
...or at least it was for me. I understand the critiques that it's too slow or aimless, but that's the point.. i'm hip to time, man.
