I haven't seen the one you have seen, but I have seen the WWE DVD and its a very good piece, obviously I wasn't a fan back then so I can't judge, but most reviews from those in the know say it is fairly unbiased, and out of all the great documentaries I have seen them do its one of the best, very tragic and moving. Also showed me what a great talent "Gentleman" Chris Adams was, I had only known him as a WCW Jobber.
