Don't expect a big beat up of Vince McMahon here. Being mostly filmed before the last damaging allegations, this is more a focus on Vince McMahons business mind - and how he swallowed the whole wrestling world under his ruthless ambition and business acumen.
It's at its most interesting giving an insight into the workings of Vince McMahons mind, he reveals more than he needs to at times (including how he has sometimes said things to get ahead and sway/program others as promotion), the other most interesting is the history of WWE. I learnt a lot although some WWE die-hards will prefer the Dark Side of the Ring.
It doesn't shy away from the allegations, and is better for it. Bret Hart, Dave Meltzer and Eric Bischoff are great interviews. Vince is too reserved at times. He's a brilliant mind, and a brilliant villian, but potentially not a good guy. Time will tell so enjoy this documentary for what it is.
