Anna is definitely relatable. I don't think Disney could have gotten anyone better than Kristen Bell to bring Anna to life. She quirky and spunky with great intentions. I also really like how the storyline is very sympathetic towards Elsa. She's not the evil older sister; she was born with powers and even though she had good intentions as a child, she was forced to hide them after she accidentally harmed Anna. Anna's memory of her sister's powers is erased after the accident (but she's allowed to keep all other memories), and when the sisters are forced apart, it was a little painful to see Anna not understand what created the divide.
The visuals are stunning with this animation. Of course I would love it if the movie was hand drawn animation, but there are some things you just need a computer to animate, like Elsa building her ice castle. That sequence was amazing. It also happened during the strongest song of the movie, "Let It Go." I mean, it's sung by Idina Menzel, 'nuff said. I was disappointed with some of the other songs though. The three I liked the most are "Let It Go" and then the beginning song "Frozen Heart" and "For the First Time in Forever." A pleasant surprise was I didn't know Kristen Bell could sing, but she can and does for Anna.
The movie is listed at 108 minutes, and it honestly didn't feel like it lasted that long. Once the story takes off, the movie moves pretty quickly. There are some witty one-liners and funny characters, but ultimately the story comes down to the bond between Elsa and Anna. I'd give this 4 stars out of 5.
