What was once profound and influential has become the backbone of much of our pop culture. Aspects of the film can be difficult for modern audiences. The film in many ways is cold and othering while lacking in the mystery and intrigue it once had (primarily due to its place in the zeitgeist).
every single thing about this movie is unbelievably brilliant, the cinematography, special/sound effects, use of music, narrative structure, enigmatic imagery, how realistically and accurately it depicted walking on the moon, 15 months before man had ever walked on the moon. it is so unbelievably visually stunning for a movie made in the 60's, might be even better than several newer movies.
