It's easier to list that movie Pixar has made that aren't incredible: A Bugs Life and Cars. Both of which are still REALLY solid movies.
The rest of their movies are fucking incredible. From the Toy Story Trilogy to Monster Inc it's just solid, funny and endearing movies one after another. In three years they'll release a currently nameless movie about Dia De Los Muertos that will probably be fucking incredible and I can't wait.
