Saw UP in a filled-to-capacity theater in Paramus, NJ. I found the story engrossing in a way that made me forget that the characters were animated. I felt like I had been transported to a magical land--a much needed diversion from the everyday stresses of life.
I will say that many of the children in the audience were constantly asking their parents about what was happening. Seems like it may have been hard to understand for younger children (ages 6 and below?).
