Big Hero 6 tales the story of Hiro a an robotic genius who like to spend his spare time in back alley robot fights. Encouraged by his talented brother Tadashi, because he is so concerned on how Hiro waste his time on this kind of activities he brings him Hiro to his university. That's when he first meet Baymax, a personal care robot created by Tadashi.

The film setting is in a fusion of Tokyo and San Francisco named Fransokyo, a very interesting eclectic environment. Don Hall directs this animated film that goes in the roots of films about a person who is search of his own identity, after some tragic happening that force him to take the lead role and encounter evilness by fighting as a super hero.

Disney exploration of Big Hero 6 is a very flat story with some nuances of previous stories. Tragedies, fight between good and evil, revenge, but most the use of Joseph Campbell The Journey of a Hero.
The problem with Big Hero 6 is not about how writers didn't developed too many layers of this story, making it meaningful, is about people, you see that Hiro and Tadashi friends developed a bond but is not that deep, which makes the whole transition to be none to be superheroes so quick that audience just witnessed in a blink of an eye. Films about super heroes take the time to show how this people transition from one personality to the other, may be is because is a kids film, the story is not a well developed. But if you see Pixar The Incredibles the story is powerful and hit the core on superheroes mythology.
