Of course she is! She was メリダとおそろしの森 enough to go against her mother, their traditions/culture and she was メリダとおそろしの森 enough to face the consequences she would encounter because of the actions that she did.
Yes, she was. She defied her traditions and culture to do what SHE wanted. That takes some guts, if あなた ask me. She helped her mother get rid of the curse SHE had put on her family. And she did it. She is very brave, hence the タイトル Brave.
To be メリダとおそろしの森 is not to stupidly rush into dangerous situations without a 秒 thought. To be メリダとおそろしの森 is to be afraid, but face it anyway. Personally, I think Merida is the prime example of bravery.
