This movie is told from the perspective of a little girl, who is forced to move with her family from a perfect life in a big house, school and friends, to a small dank house in the city with no friends. Except its also told from inside her head, with her various emotions; Joy, Sadness, Disgust, Fear and Anger. In Joy's battle to keep the little girl happy, things start to change inside her mind and they get lost on a journey around her memories. There are some very clever ideas on show here, which is why Pixar will always trump Dreamworks, you have great animation, in jokes, but also a very original story. Some of the ideas might even be a bit too advanced for kids, but adults will get them along with the usual in-jokes. It does start dragging very slightly as they work through the zones of the brain, trying to catch the 'idea train' back to the core, but this is slightly rescued by Bing Bong, the talking elephant/cat thing! With slight trimming this could have been perfect, but its still the best animated film this year!
