Art should inspire. While he likes to find all three components in a film, he believes that education and entertainment are more accurately labeled by-products of good art. It invites others to explore and to find the same insights, sometimes to discover greater or altogether different insights. Art doesn't aim to teach, but experiencing it can be educational. Something is entertaining because it is, in some way, good at something.
Art can be entertainment.
But so can sports. Even television commercials. Unfortunately, 'entertainment' has lost its real meaning and has come to mean escapism. In the same way, education no longer suggests mental stimulation or the enabling of minds to develop and think for themselves. So it has fallen to art to pick up the roles shed by entertainment and education.
