The action is non-stop in this fast-paced, hilarious and touching story. “Monsters, Inc.” is refreshingly free of any suggestive elements, foul language or crude humor. There are some comical, scary scenes and it’s filled with threatening chases, wild rides on a conveyor belt, some struggles and mild fights. Scenes where Mike and Boo are threatened by an ominous machine could upset very young children. So, with a cautionary note that some scenes may upset very young children, “Monsters, Inc.” is a welcome addition to family entertainment.
