Essentially “Home Alone” with a mouse, early test screenings brought back some of the worst audience test scores ever. Besides the fact that most family films rarely feature inappropriate sexual humor. Sexual humor?! In a children’s film?! Hello! Who was asleep at the wheel when this film went into production? And what is Christopher Walken doing here? Clearly, the filmmakers should not be making children’s films, let alone be left in a room alone with any kids. Just plain bad.
