I haven't seen the film yet but I remember hearing an interview on PBS about the film a few weeks ago. I don't recall hearing the detail about the writer's father's insider status, but it doesn't surprise me. It sounded like a very good film but perhaps somewhat like The Social Network was a good film while still being a particularly slanted story that focused on people rather than an industry. I suspect a lot of it is very accurate but because it focuses so much on individual actions and behavior, but fails to pull back and look at the system as a whole and how it made such an outcome inevitable.
