Big Hero 6 (2014)
I somehow missed all mention of this when it first came out. It’s a computer-animated Disney/Marvel film set in a parallel universe version of San Francisco that’s heavily influenced by Japanese culture, having been rebuilt by Japanese immigrants after the 1916 earthquake.
The protagonist is a 14-year-old named Hiro, whose older brother Tanashi is an engineering student working on a medical robot designed to be big, soft, and comforting. Hiro eventually becomes the leader of a team of high-tech superheroes, and while the story isn’t entirely predictable, there are a lot of clichés and intended surprises that aren’t likely to surprise anyone.
On the other hand, the flaws aren’t so awful and they’re offset by some nice bits and excellent animation. In the end I rather liked it.
