The Day the Earth Stood Still Reviews
This particular example is a very strong movie of its kind with eerie music by Bernard Herrman and nuanced direction. People back then did these movies impelled by the true feeling of dread of nuclear annihilation.
I thought Michael Rennie was good as Klaatu. He had an alien demeanor to him that was almost robotic, but there was also an underlying softness that took off some of the edge when he was interacting with other people. Child actors are often a struggle for me, but I enjoyed Bobby Benson. It's certainly in the golly-gee style of many 50s kid's performances, but it seemed to fit with this movie and his role in it.
I couldn't help laughing at a few of the ways life was different back then. For instance, when the Mom allows her son to spend the day with a stranger touring the city. Also, the police seemed entirely too laid back and relaxed when tensions were escalating. The nature of Klaatu's mission is a little odd when you actually think about it, but I got over it quickly because the message he delivers had significant relevance to the original viewers of this movie.
It's a film that I did enjoy to a point, but it didn't impress me in any significant way. It possibly suffered a bit because I literally saw it only a few hours before I went to see Arrival in the theater, and that movie has some similar themes but is more nuanced in the way those things are handled. I'd probably watch The Day the Earth Stood Still again if asked but it won't make my list of favorite science fiction films.
