I need good CGI animated movies?

my sister and her (7 year old) kid are staying at my place and i've been watching a movie with my nephew every day. He only likes to watch the CGI movies, and i'd like on that would at least somewhat interest me. so far we've seen Cloudy with a Chance of Meat, Monsters vs. Aliens, Ratatouille, and Bolt. there's still 3 more days left until they leave and i'd like some opinions.
