Fantastic Mr Fox takes a charming Roald Dahl short story and draws it out for an hour and a half by providing various back stories (Mrs. Fox's racy adolescence, the Fox's son's teen angst) plus the addition of an unimagined (by Dahl) cousin) to stretch out the action. The animation is great and the script is often very funny. Having George Cloony and Meryl Steep's American accents is fine, given that they are speaking "Fox", while the villains are speaking British. Three generations of viewers all agrteen it was worth seeing but not not nearly as memorable as "Up"
