Technically, Monsters University is a prequel and not a sequel, but we’re not going to split hairs. It came out after the original and tells a new story in the world, so it’s close enough. It’s a fun enough movie on its own and it does show us how some of our favorite characters got to where they were in the original Monsters, Inc. However, one does have to ask the question, “Was this a movie we needed?” (I’m not sure it was.) It doesn’t really add anything to the grander story of the monster world, and it even retcons aspects of the first film simply by existing, making it clear this idea was conceived entirely separately from the first movie. Who cares? It was nice to see old friends again.
