While this is not the definitive Science Fiction movie or the greatest movie ever made, the questions and topics it covers are astounding. It’s got some great acting, a brilliant script and good directing. The visuals aren’t timeless, but they serve their purpose and get the job done. Klaatu and Gort are characters that everyone will remember and carry such weight in what they stand for. I’m sure that in the 50’s this was incredibly surreal and frightening, the Cold War aspect is perfect and way ahead of the social feelings of the time. It’s a Sci-Fi classic and unforgettable.
