What's yours and why? For me it's Mr. Holland's Opus. I was the band/orchestra ultra geek during high school. I ended up being personal friends with the band and orchestra teachers once I grew up and was no longer a student, and as a student I remember liking it because instruments, and my teachers loved it, and we would watch it on occasion in school with the music teachers when we had a free period. As a teacher I love it because of the character arch of Mr. Holland realizing his actual dream was what he had always done. I know a lot of teacher movies are irritating because they're not super realistic, but if you had to pick one, which would you?
