I dunno, while this film is good (from reading the stuff), Brave definitely deserves the flak it gets.
I'm not referring to Brave's quality as a film, just that people like to make out as if it is so progressive and revolutionary and use that as a stick to beat other 'Disney princess' movies with. And I sense this annoying narrative continuing with Frozen.
As an aside, Brave still received fairly good reviews and there is a very realistic chance Frozen may get a similar level of critical reception, early reviews tending to be more positive.
As another aside, though I get some sick pleasure from seeing Pixar get bashed, I like Brave and don't really understand why people seem to have so many issues with it.
