I have watched all 6 episodes, there is nothing in any of them that isn't already out there, disappointingly. Personally I really was hoping to hear about his childhood because his lunatic personality and quirks have all got to be linked back to that. Why wasnt his dad around? Where was his older brother also? What was he like in school? Did he have any friends who remember him today? Apparently he had a stint in army, where supposedly he got into trouble.
Clearly the original idea was a celebratory puff-piece and that still shines through, even though the makers have tried to be more balanced. The only time I remember him being challenged on any of his utter BS is when it's pointed out that WCW only did to him what he did to all the territories. Other than that it's just him making an arse of himself with his total lack of self-awareness.
