On that note, youthful inexperience and insecurity seems to be a big theme in Episode VII, on both sides. Rey is holding onto a childish and willfully naïve hope that her family will come back for her; Finn blusters and bluffs his way through his adventure, motivated through most of the movie by his own sense of self-preservation; Kylo Ren is the biggest example of all, having a poorly-built lightsaber which reflects his own instability and prone to immature emotional outbursts. Rey and Finn are new at being good guys, and Kylo is new at being a bad guy.
