A romantic comedy long on sentimentality but short on jokes, this is a vehicle for the ungainly, overweight Kevin James, a specialist in roles as supposedly lovable all-American slobs. Here, he plays a caretaker at Boston's Franklin Park Zoo who, having been jilted by his girl, is instructed by his friends, the menagerie's talking animals, in how to woo her back using the mating techniques of the plains and the jungle. I would rather lie on a bed of nails watching Dr Doolittle for a week than see a single reel of Zookeeper again.
