I just saw this today. As a side-note, the animated short The Feast was absolutely awesome The movie itself I liked more than I expected. Admittedly I'm a little tired of the superhero thing, but this felt both fresh in some ways, and tired and used in others.

I won't say too much, but the relationship between Hero and Baymax is a really nice one, and there was a lot of very enjoyable humour. Overall, I really liked it, and I would recommend a watch. Then again, I'm one of those heathens that didn't really like Guardians of the Galaxy (when everybody else loved it), so take it with a grain of salt.
