I agree with the film critic from The Telegraph: this is the best work of animation from Disney that I've seen in years. I saw it twice in the theater--the kids enjoyed Wreck-It-Ralph, as did I, enough that we went to see it two times during the holiday season. Both times this little film which played before Ralph, like the best short cartoons, simply melted us with its humor and beauty. The technique behind it--read the above article to learn about the new software used in making Paperman, or read this interview, or watch this video--is fascinating: actual hand-drawn flourishes animated on top of the CGI base. There's a wonderful style to it, and reading through the comments on the blogs reveals all sorts of at first unnoticed touches: the shape of the characters echo Aladdin, the paper airplanes hearken to the opening of Fantasia: 2000, and the hero's boss looks like no one so much as Bryon Brassballs from Dark Knight Returns. Endless levels here--which is what the best art is supposed to provide. Anyway, enjoy.
