If you've never seen Big Hero 6, or as my son calls it 6, you really should see it. But I must warn you your kid may become addicted to it, like mine. Lol.
It's about this boy Hiro and this inflatable robot Baymax who team up with a group of friends to form a band of high-tech heroes. There's not much more I can say about it without giving away some of the story.
It's super cute, has great music, and even has some good lessons in it. If you haven't watched it yet I hope you will soon.
