It Came from Outer Space (1953)

The thoughtful saucer movie. Built from a film treatment by Ray Bradbury, it imagines visitors stranded in the desert who mean no harm, which turns the usual invasion story into a plea for patience with strangers. Jack Arnold directed it as Universal's first film in 3D, so the meteor crash was made to come right at you. Even flat, the empty desert at night is genuinely eerie. A good pick for viewers who want ideas with their chills.
