For a wrestling documentary, it's no "Beyond the Mat" but come to think what is. It's on Netflix streaming. I watched it the other day & it nothing I'd go out of my way to watch but if you have 90 minutes to kill it may be worth checking out. The main star is Kevin Sullivan. It covers the world of independent wrestling, mainly an organization out of New Jersey. Also included is one of the last live interviews with "Sensational" Sherri Martel.
I have this on DVD. Most of "Inside Indy Wrestling" on the National Geographic Channel was from this documentary. Personally I really like it and highly recommend it. As someone who attends several indy shows in California, it really captures the reasons I am a fan. Tyson Kidd informed me he likes it too, for what that's worth.
I think it's neat that DiBiase's back with WWE, even though we probably won't see him on camera until he gets voted into the Hall of Fame. Which I imagine will happen sooner rather than later, and rightly so.
