The worst example of this is the mis-use of a song and artist I like very much. It's also a film younger viewers should see for its message. I hope they don't become too tolerant or hack film-making because of movies like this though. A lot of people aren't going to notice how several scenes seem inserted as little exclamation points between other scenes and put characters together before they have developed any respect for each other or while they are building bridges. You see if you don't like someone very much or fear them, you aren't going to go out of your way to have long conversations with them apart from other people in public places.
People notice, gossip etc.
We also have no idea what happened to the black high school or the former black coach. They don't need to be explained too much because you know who they are already. There's also just one memorable female character in the entire film. She's an obnoxious little girl who is an unsportsman-like sports fan screaming at her coach father and players from the sidelines at practice and at first exhibits racist tendencies. She's used as a device more than a character and it spotlights how so much of this film is made as a tract for it's important message rather than an important film with a message.
