I have heard that before. But most people say that only the first movie has the bad research, because it attacks religions. I haven't heard much dispute for the second and third movies, which is what I am talking about.
But I think the core of the economic model presented in the second and third movies is sound, if a bit naive. I encourage everyone to see at least the third movie and make up their own minds whether the alternative economic model presented makes sense.

to know what I mean. I don't know much about these things, but the two movies have certainly raised an interesting question about money and sustainability, at least in my opinion.
even scarier is the Zeitgeist 'Federal Bank' film. I dont really understand how the economy works, but this film is an eye opener. If you have time to watch the other parts, part 5 is scary...very very scary if it actually happens.
