Accuracy is always a plus, but its not essential. Shit, look at Oliver Stone's great but incredibly incorrect JFK.

I'm just commenting that Jimmy Hoffa is one of those incredible "small" stories in American history in the 20th century, but when a History Channel, 1-hour documentary is more compelling and enchanting than a 140 minute expensive movie with Nicholson and David Mamet scripting.....

Let's just say that the movie has problems.
