This is one of Best animated pictures ever made. I don't why the contemporary critics didn't like this movie. It definitely deserved the Oscars that year. Giving the award to any other movie that year was unfair.
It's the ultimate movie about returning home. When you yearn so badly about coming back home, but have to put your head down and earn your way back. It is like earning your right to be free.
Pure, uncluttered, unadulterated movie. No sidekicks or stupid subplots. I like this kind of movies.
