Great story, at least with regards to Pixar stepping up the way they did. I really like their films a lot because of the heart warming and inbuilt themes of hope. It's sad to think that a little one can suffer and die so early and I hurt for the family. At the very least, I think stories like this remind us to be thankful for what we do have.
On a lesser note, I did see this movie and it was really well done. It had a great theme and I can see where a 80 year old and 5 year old alike could appreciate this picture.
