Read this review by G. Edward Griffin. He is a real expert in the field and wrote the book The Creature from Jekyll Island (Probably the best book on the Federal Reserve). The movie has a lot of good parts in it but it does a bad job of giving an alternative.
it was even more dissapointing to see them jump on the fiat-money bandwagon as a so-called solution to the banking problem. Yes, they actually propose that the solution to fiat money created out of nothing by the banks is to have fiat money created out of nothing by the government, as though politicians are any more trustworthy than bankers.
