Whenever I watch a really good animated film Im always impressed by the effort that goes into them, all the balloons on the house move independently, its amazing.
I loved the film although, but it was so sad when his wife died, I dont need that in a Disney, its like when Mufasa dies in the Lion King or when the Fox and the Hound get separated.
If you can take a bit of heartache in a movie, make sure you watch UP, its brilliant.
