The film has so much care being put in it's story with interesting characters and villains, and comedic scenes. Up does a spectacular job at making the watcher feel sad for Carl, showing his childhood first you'll think he'll be happy, but he ends up becoming a grumpy old man. His backstory is emotional and happy at the same time. It's one of the only parts in a movie that I've cried at. Seeing Carl opening up to buddy, Kevin and Dug is just amazing. A twist villain in this really surprised me, you can feel that he truly is a broken man. Searching for Kevin for like 100 years and Carl just walks in with him. I could say this about any movie but this one just flies above animated movies like a god.
