This "doco" is more "mocko". The people whose lives are tracked throughout the film are caricatures, I suspect cast purely for comic effect. Classic exploitation. That aside the film does make for some enjoyable viewing. At times I wondered whether the film was straying into the realms of snuff and thought 'why don't the filmmakers step in here'; but on balance, understanding the difficult decisions they face, I think they acted appropriately by not disturbing the natural order.

If you're comfortable laughing at others' expense and don't lose sleep over unanswered questions (like why the film is called Fargo, what happened to the buried loot and did Frances McDormand's performance really warrant an Oscar) then it's well worth a watch.
