Wow! I never knew they could take a kid's story and make it so cool! At first I thought it was going to be another one of those Toy Story wannabes that pushed the graphic element to try and sell the story, but there was a lot of funny dialogue and a plot twist that was totally unexpected!
For those that don't remember the story of Chicken Little, he was the little fella that ran all over town yelling that the sky was falling when it turned out to be nothing but an acorn clunking him on the head. The story begins there, for the first five to ten minutes, then takes off on a whole new tangent. The character development was amazing for a "cartoon".
I'd recommend watching this one, if you haven't already. It's definitely one for all kids, old or young!
