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.
Yeah it was a shame that such an awesome wrestler like Gentleman Chris Adams was reduce to a jobber role in WCW, however, that was case with some of superstars that come out the territories and found out that they did not what it took to make it in the WWE or WCW. To be honest with you I thought Chris Adams could have made it but he did not make it like he did in the WCCW.
