The only version I have seen of this is drastically abbreviated (23 minutes of the original 97) and so very difficult to assess in any way. Several of the action scnes (the mountain scenes and the floods) are very well done and it would have been nice to have seen the whole film, a very major and ambitious production at the time. As it is there is a pretty good Russian version of the story from 1937.
