Having so fervently championed the cause of peaceful co-habitation, it's more than a touch disappointing that the fourth adventure featuring Fievel the immigrant mouse should contain a number of flagrant racial stereotypes. Moreover, it also includes three dreadful songs and a transparently obvious mystery. Along with his faithful buddies Tony and Tiger, Fievel allies with The Daily Nibbler's ace reporter, Nelly Brie, to investigate a sinister series of mouse-nappings. But, apart from a couple of imaginatively eerie dream sequences, there's little here to hold the attention of even the least discriminating kid.
