The entertainment a violent, selfish person like Trump can offer his supporters is nothing more than a fight. Trump is losing control and will affect much of the world. It will take a long time to determine whether what he says is a joke or a reality.
Good, honest, and intelligent people don't want to improve or govern society. They understand the difficulty of being fair and dealing with people. Without them, selfish, evil, and filthy people begin to rule countries. Consequently, the film ends with a bang and a storm.
