'Zookeeper' is a broad family comedy starring Kevin James as a lovelorn zoo caretaker whose animals, secretly able to talk, decide to help him win back an ex-girlfriend. Featuring the voices of Sylvester Stallone, Cher and Adam Sandler as the various creatures, it trades entirely in slapstick and toilet humor. Critics savaged it as lazy and charmless, though it found a modest audience among younger kids. It stands as an unremarkable entry in the wave of formulaic talking-animal comedies of its era.
