Another movie where one of the main characters dies at the end..........Must have been a trend.............
It is the only way any such movie can end. They are not trying to opine on the meaning to life of to show life has purpose and define it. In all these movies, the protagonist is futilely searching for meaning and purpose in his life and never finds it, leaving nothing left but useless, purposeless death.
It would be a long movie to have them die naturally at 70 years old, so to cut to the chase that death is the only reality, they all have to end with the protagonist’s violent and meaningless death, often at the hands of the “evil” establishment or some other group or organization the protagonist feels is the root of all evil in life. That a can be the FedGov, a church, the military, a strict father, a school principal — whatever represents a moral authority being imposed on the character, who is seeking meaning in chaos and lack of moral boundaries.
