The ending of this film has to make this one of the most realistic war films I've seen. It shows the horror & brutality of war in a 'simple' scene showing civilian casualties. I suppose this film could be seen as propaganda but as China was the underdog in this scenario I think it would have been very moving & filled me with patriotism at the time. The final scene is extremely moving & very interesting historically & technologically.
This is the only feature-length silent film I've seen so far that I would consider watching again - although it isn't completely silent as it was dubbed with a few songs & some sound effects.
