Can you provide some historial & economical context ? "Was horrible" doesn't say much.
There has been a long time since I saw the movie but let me give you a quick list (if you are really interested in some area I can dig up and check some reliable sources about some specific period so you can take your own conclussions):
- Several of the quotes he uses on the film I found to be undocumented and dubious, f.e: Widrow Wilson saying at the end of his career that he regrets creating the Fed. It seems he never really felt sorry about it..
- During the Lincoln era he seems to imply that he was killed by the bankers because he wanted to keep printing and bankers did not want to. The reality is that the greenback was hyperinflating and the only way to avoid it was to stop printing it. Also, Lincoln approved a banking act at the end of the war that centralized the credit in the banks of New York, so bankers were happy about him.
- Then he talks about the silver thing like if it was a popular movement, when in reality it started as a industrialist thing. Actually all that part is horribly explained, and he talks about it like if it was a big crisis and then suddenly after some few years the USA has become a industrialized nation. It does not make sense, because it did not happen that way.
Etc...
As I said, if you are interested in some specific period I could look for some references so you can read and make your own opinion.
