I watched it in the theater with a comrade, and I had a hard time explaining it to them afterwards, that while I liked the movie, I didn't think it worked as a teaching tool, like I kept hearing.

Everyone is just going to associate with the class they think they're a part of, excusing their bad bits and inflating their good ones.

And sure enough...

It's still a great film. It just doesn't have any pedagogical qualities, imo.
