I enjoyed Brave but it wasn't without a few flaws.
First of all, I never felt like there was much meat to the story. It was enjoyable sure, and had some good morals and family values but I never felt like I was invested in the main characters. Stuff just seemed to happen.
Secondly, and this isn't as much the movies fault as perhaps the marketing that surrounded it, but it was actually a very different movie than I thought it was going to be. I discovered that it's hard to break those pre-conceptions as I kept thinking the story was going somewhere else than it did.
