In recent Disney Animations I feel that the plot is more developed and brings a lot of stimulation to the viewers. I first noticed this with Frozen. Instead of the bad guy being introduces to the view as soon as the movie starts we have to figure out towards the end who really is the villain. In Frozen's case it was Prince Hans.. Which I didn't really see coming.
In Big Hero 6, it was even more complex... First, you have Hiro and brother Tadashi both geniuses. Then the relationship between the Professor Callaghan and Alistar Krei. The relationship between Hiro and Baymax. Then we come to find out Yokai's connection to Hiro and Alistar. All very complex and a bit confusing I might add, but extremely complex. I enjoy movies that do not provide me with enough information to know what is going to happen next.
Overall, this movie was a touching movie. As a young adult I never get tired of watching anything cartoon, disney, or animation related. Disney just keeps getting better from animation, to story complexity, and for filling the audiences enjoyment.
