The 400 Blows
Saw it last night. I felt bored throughout, but when it was over I realized how affecting it all was. It was as though I only thought I was feeling bored. Seems weird, but Truffaut fully crystallized the flick at the last moment without really changing anything (i.e. it was not The Sixth Sense). It was like a slap in the head. "SEE?"
Yet another nail in the casket of causality.
