Potemkin is one of those movies that was influential and left a lasting stamp on every film that came after—but the film itself is rather dull, IMO. I believe Kubrick also felt that Eisenstein lacked substance, so I’m not alone.
Unless I’ve missed it, no one has mentioned “Mr. Deeds Goes To Town”.
I would have agreed with you until I saw Battleship Potemkin accompanied live by the National Symphony Orchestra, as it was intended to be seen. You couldn't move from your seat; and the last scene with the bow of the battleship plowing straight into the camera at the same time the orchestra reached a crescendo left everyone stunned for minutes after the film was over.
