Walt Disney Animation just posted the first clip from it's upcoming Big Hero 6. Like a lot of marketing for the film, it relies heavily on the adorable robot Baymax. And we're okay with that.
The clip doesn't reveal much of the plot, but it does put on display the Hiro/Baymax relationship that is the heart of the film. It also makes clear that Baymax is a little too overprotective to make a great doctor.
