Perhaps you expect the film to be about the plot. It's not. It's an entirely visual exercise, and, as I believe Kubrick said, "Nothing important [in it] is conveyed in dialogue."
That's why it is such a bad film.
So every film from the silent era is a bad film, then.
Who said that?
Oh, right, you did.
, for example, manages perfectly well to convey and explain its story in images and (written) dialogue or scene descriptions.
fails there completely. The film doesn't explain why
things happen, it only shows that
they happen. The result are beautiful but boring images and question, lots and lots of question which are never answered in the film (and which arise not only because the viewer falls asleep 45 minutes into the film).
