The future is an afterword. The good guys won and have been living in their own world without violence for a couple of years.
This season, the series is removed more as a benefit for schoolchildren. Each of them has a certain problem, it is revealed, even gets some material image, and then it is overcome and draw conclusions. The message is chewed more thoroughly than ever before.
In order to demonstrate problems in relationships, the writers almost deprived the characters of personalities and greatly reduced their intelligence. Gems (immortal inorganic guys) with some kind of fear begin to fear snakes, and in the process of his reflections Stephen breaks the fourth wall. It was terribly boring and long.
A nonviolent agenda leads to strange logical twists. In one episode to protect the planet from two gems whose job it has always been to destroy these planets, Stephen tries to convince them to do anything, but to no avail. To “incline” them to their point of view is obtained only from his assistant, who just piled troublemakers. The case is done, but she has to apologize and repent for the use of violence to Stephen, who condemns this approach.
Losing the planet or beating up abusers is a difficult choice.
In the end, the grown-up useless Stephen goes to travel the world. The people of the town, of course, sorry to say goodbye to him, but, I think, he is already quite annoying, even in the film crew.
Such is the disappointing outcome of this attempt to portray an ideal, tolerant world without violence.
