While Disney was predominantly a girl studio, Pixar has been a boy studio run by nerds. Brave is a half-hearted attempt to break into the princess market with the story of a princess of a Scottish Highland clan. But she's a peevish tomboy who likes shooting arrows more than girl stuff, identifying more with her barbarian dad than with her educated, managerial mom. The Celtic setting is interesting (see this post) but the storyline doesn't make much use of it, instead being a generic suburban tale about a self-absorbed adolescent who doesn't appreciate her mom enough.

Brave is not terribly funny and it's not a musical, so it's not as entertaining as the best cartoon movies. Also, the look of the characters appears to be modeled after those plastic  so they are fairly grotesque to look at. Fortunately, part way through, one of the characters gets magically turned into a realistically rendered bear with a nice fur coat, which is easier on the eyes than all the humans.
