I am a little late with this review.... but what a great movie. Pixar has done it again.
The whole intro with Carl, the main character, meeting his wife-to-be was so well done. Pixar does such a great job at telling a story with nuance without spoon feeding the audience with dialogue like most movies. We totally understand why Carl has to go on the adventure, as crazy as it is.
I also like the contrast between Carl as an elderly person and Russell the energetic "Boy Scout". Carl used to be Russell when he was younger, yet sees Russell as a nuisance at first.
The movie was so special, I really don't want to spoil anything who may have not seen it yet (including my wife :) ).
I give the movie 4 out of 4 stars. I can't wait to buy it on disc.
