Aleksandr Dovzhenko was not a bad director but I consistently find his films to be choppy, poorly-paced, and fairly uninteresting, making him one of my least favorite propaganda filmmakers. Of course, many would attack me for daring to dismiss Dovzhenko as merely a propaganda filmmaker, but all three of his films that I have had the chance to see have undoubtedly been propaganda, although "Arsenal" is perhaps less obviously propagandistic than "Earth" or "Aerograd" are.
I call this a near-masterpiece because of the basic purpose of it, which is propaganda. This film exists as agitprop, and while it contains phenomenal and ferocious imagery, ultimately the single-minded viewpoint hobbles it as art and undercuts its slight attempts at humanity.
For several years I had a decent quality print on video and was always fascinated by this film. Very few motion pictures are as visually striking and intense, but little of the story came through.
