People are voting emotionally.

This is a tender, generous movie that likes its characters and presents them as real people, full of flaws and strengths.

This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

There are moments in this movie where the great movie it could've been peek out... They're fleeting, here, but they're worth savoring, and they happen often enough to make it worth your while.
