In the world of Brave, it's a place where Mulan and Ariel (of the Little Mermaid) will be seen as role models-- female teens with parental issues that try to take control of their own respective destiny will thrive. But it's also a place that you forget immediately after the initial visit.
Merida (voiced by Kelly Macdonald) likes to see herself as an anti-princess. Instead of the fine arts and sophistication, she prefers to shoot arrows and eat like her boisterous father, King Fergus (voiced by Billy Connoly). But when the dear mum, Queen Elinor (voiced by Emma Thompson), imposes that Merida must follow tradition, that's when the interesting bits start to happen.
I must say that the folks at Pixar did a wonderful job keeping what this film is all about. Themes of child versus parent and age-old "be careful what you wish for" lesson are at the movie's core, and wrapped by the lush countryside. But I won't spoil it.
What I will say is that after the movie, Brave tries its best to take the princess template and shatter it to a gazillion pieces, but loses the fun element in the process.
