One part i like that movie; when Brad Pitt went to a store and he grab that cashiers guy and took his wallet off and he found out that he is a medical graduate but stayed as a cashiers in a store.
I can't imagine myself being a medical graduate and ended up working as a cashiers in a store. That movie alone is a worth of a life time moral lessons, the idea itself covered most people and the world and it will stay for a while for another decades, that way newer generation will learned from it and became aware and enlightened from the our reality we've been through.
