There are exceptions like Mr. Holland's Opus. But the rule is Arnold in Kindergarten Cop. For their part, students are depicted as at their most alive when they have as little to do with school as possible. Or make an Animal House, and trash the joint. Not that the derision is difficult to understand.
Education is a setup for ridicule.
Old people stuck in place deliver old information to new people about to move up and out. The adamant vs. the supple. The strait-laced vs. the unlaced, over whom they exert a flimsy and temporary authority. Every classroom is an implicit smirk. I'm going to leave him in his own dust.
