The most incredible case of teacher malpractice I've ever heard of, came from my son. He was in college, taking a film class, which is my son's expertise. He's a deep film guy, for real. He could literally teach it, so he doesn't tolerate nonsense from bad film teachers.

So this teacher showed a clip of The Color Purple, and proceeded to criticize all of Stephen Spielberg's artistic choices, painting him as a hack. Spielberg isn't my son's favorite director, but he respects his talent. He doesn't believe that Spielberg is a hack.

But a stupid conclusion wasn't the problem. The problem was that the clip the teacher used to illustrate Spielberg's poor directing, was taken from the terrible remake of it, which wasn't directed by Spielberg. The teacher criticized Spielberg, using a movie Spielberg hadn't directed. And it turned out that the teacher hadn't known there were two versions of The Color Purple, nor that there was a musical, either.

This was in a COLLEGE film class. My son was disgusted, and I thought it was unforgivable, and told him to report the incident, but he didn't. He just pledged to never waste another course on that professor.
