Saw this yesterday and have to say this is a great movie. Beautifully realized, with a great story, great voice acting...you name it, it excels at it. A princess movie for the whole family. Pixar shows how to handle CGI humans once more. By creating appealing animated designs, and NOT trying to make them exactly like a live-action actor, they seem more alive, and MUCH less creepy. The computer-generated scenery is just stunning.
After their slights stumble with the very mediocre Cars 2, this puts them back on top. The opening short, "La Luna" is also very well done.
Go see it!
