Why would you say that video games and animes are better off as a series than as movies? Especially when you consider the recent flops of Ghost in the Shell and Assassins Creed?
Come to think of it, anime characters exudes a real life personality that makes them relatable. When they're mad they're mad, when they're sad they're sad and when they're happy they're happy. Anime figures really care about other people. Take Goku who trains very hard so he can be strong to protect his friends and family. At one point he decided not to be brought back to life using the dragon balls as he feared that his revival would only attract more danger.
