Kind of surprised so many think 2001 is just "fine" when it's possibly the best film ever made.
Even if someone didn't like the story and subject (that is more relevant every passing day than it has ever been) the artistry of the filmmaking is one of the greatest achievements in any artistic human endeavor.
Yeah if you're looking for rom com, a college humor movie or an action movie where everyone gets shot it's not your movie. In terms of "great films" it's almost undeniably top five by any measure.
Even if the entire movie was just the 30 seconds or so where man's first use of a tool spinning in the air jump cuts to a spinning space station...even if the whole movie was just that one shot...it'd still be one of the greatest things ever put on film.
Didn't even mention the music yet.
2001 is a great film. I feel the same way about FMJ.
