Quite right, a film is never going to show someone getting it wrong. The post is more about thinking about ideals, and why they come across that way. But I'd like to come back to the point about trying and failing. Until recently, when you wanted to change a font in a word processor you never got any preview, you had to select it, if you didn't like it you had to undo, and then reselect again. This is the sort of thing I was getting at.
