Perhaps the first sociological science fiction film, probably one of the best overall. A story like this could have made Kubrick jealous. Spielberg domonstrated the emotional power of an image: thrill and fear in the two Barry kidnaping sequences respectively, the ecxitement of what is unknown in Rory's close encounter, the sadness of the downfall of a family and many others.
This film is a pure mix of the best elements of science fiction pur together.
