content: Patty McCormack was only a little girl when she appeared in this movie, but she already had plenty of acting experience, having played the same part in the stage version.All of the actors in this wonderful movie do outstanding jobs, but Patty is simply outstanding.The story,as the title suggests, concerns heredity. Does the bad seed of a parent actually pass on and influence his or her child?Aside from Patty's remarkable performance, there are also standout acting jobs done by the wonderful Henry Jones and Eileen Heckart.This is a spellbinding movie, and I never get tired of watching it over and over again.
