Mirai ends better than it begins and benefits from some touching moments and great animation with some really nice sentiments on family and youth, but the films repetitive structure and main character hold it back from being better.
12 Angry Men is a film that starts strong and ends strong. A true tour de force in every sense of the word. There is nothing that will change my opinion about this movie. You could talk for a hundred years and you wouldn't change a thing.
