In the story, a 14 year old robotics enthusiast, Hero Hamada, a young genius on the subject actually, is pulled out of a dead end life fighting 'bots by his big brother. The caring older brother introduces his younger sib to a college institute for robotics and some truly talented students there ... plus a groupy who provides comic relief. There the young man also meets his older brother's robot Baymax, designed for healthcare but capable of much more.
Adventure ensues with plenty of humor and fun. If you want casting voices and other information, try Google. I'm in a hurry.
Interstellar, the sci-fi wonder fest, is worth seeing as well. It is filmed partially in IMAX and is startlingly gorgeous. It deals with the topical issue of global warming and a future generation (not that distant) that has used the planet up. The main character's, Cooper's, generation will be the last to survive on a planet turning into a large dustbowl. In this future, the technology revolution has collapsed. History textbooks are rewritten, stating we never made it to the moon and the entire attempt was propaganda designed to get the Soviets to spend themselves into oblivion on useless rocket tech. Cooper knows better, being one of the last NASA test pilots, who now must grub out a living as a dissatisfied farmer.
Cooper gets one last chance for space to try to save his family. The film is character based and driven, making it a good story you can get absorbed with and providing characters you'll care about. It is also worth the expense of IMAX for this experience.
For me the only downside of Interstellar is the use of postmodern claptrap to explain the metaphysics near the end. However, if you are a sci-fi geek like me, you've seen this often enough before not to be surprised or too badly thrown. Give Interstellar a try.
Both films are worth the time.
