The script for Lyle spends more time around the family that moves into the apartment Lyle began to live in when purchased by Hector P. Valenti (Javier Bardem), purchased him from a location that sold unusual exotic animals. When Lyle refused to sing (he is a singing crocodile) he is abandoned in the attic of the apartment as the Primm family moves in.
A sad and lonely Josh the Primm’s son is uncomfortable with moving to a new neighborhood, city and school. Finding Lyle living in the attic changes Josh’s attitude about everything and it all heads to a very satisfying ending. We have seen this scrip a number of times before and even the smartly animated Lyle doesn’t bring enough creative difference to carry the film.
