I went to a double feature because I wanted to see The Tin Drum. First I had to sit through another movie I had never heard of that sounded really corny: Runaway Train.
Starring John Voight and Eric Roberts, and with a screenplay by Akira Kurosawa, it was extraordinary. Certainly not just a cheap action flick.
I think that's part of the puzzle is definitely that small children don't get embarrassed or ashamed if they make a mistake. Adults and older kids do, so they stop trying or they limit themselves to what they know they can do well.
