The USA is founded on emigration. On people coming to USA to seek their fortune and thus providing the labour, on which the modern age was build. That's a lot of eyes, but unfortunately the stories told from those days are mostly the same, and in the same historic perspective.
This movie narrows the focus to depict a fragment of the battle to define exactly what democracy is - and who gets to define it. Labour unions are at the forefront of this battle, recognising the oppression that makes a few people very rich and powerful enough to bend the government. For example the banker J.D. Rockefeller, who was able to call in national guards to terrorize and kill his striking miners, who were kept under slave-like conditions.
One can never see the whole of a story, without losing important details. But "No God, no master" manages very well, I believe, to show how both the powerful and the powerless are only just people, and how bridges of understanding can be build through simple acts of diligence and kindness.
Besides being presented with a less knows aspect of the story of how the nation was build, I loved the feeling of being "back then". Indie movies can't recreate and build fake streets, but rather than resorting to CGI like many Indie movies (and over-funded movies too - neither with quite satisfactory results) No God, No master makes do with camera angles, select streets and plain good storytelling in frames to create the illusion of streets from a 100 years ago.
My only critique was a tendency to take "tension music" right to the edge. I would say this was unnecessary as the plot was sufficient to keep me interested and leaning forward.
All in all a decent movie I have no problems recommending. 7/10 for just making a good movie.
