What is a jung archetype, what is the Hero's journey? What makes a character arc? None of these characters follow one. Rey is given super natural force ability and is and has been a Mary Sue. She then beats Kylo Ren multiple times for what kind of progressive arc in upcoming films?
Finn was a janitor turned side quest fetcher with plot lines no one cares about or think should be in the films.
BB 8 is product placement.
