At the very least it is unusual for a feature animation film targeted at the family market to be focusing on themes like midlife crisis, marital problems, bad parentage, impotence, fashion faux pas and job worries. And also to be very neat send-up of a mainstream modern American life. What’s more unusual is that this satire comes from the crucible of animation experts Pixar, who have so far introduced us to living toys, talking fish and human-like insects. But with “The Incredibles” these creatives are stepping out in a new direction.
