Kathryn Schroeder of FilmFracture writes: "Zookeeper is essentially a romantic comedy that plays by all of the generic rules of a lackluster, formulaic romantic comedy. The spin is of course the talking animals who give Griffin advice on how to succeed in wooing Stephanie back into his arms. Animals may not be too keen on exactly how to woo a human female, and this then leads to a variety of scenes where you watch Griffin imitate, act like, or mimic different animals. In a perfect world these scenes would be hilarious. In reality they exist to make Kevin James make a complete ass out of himself, without any semblance of humor whatsoever."
