JVK echos a lot of my thoughts on this. Haven't listened to what Dave said yet.
It would be a MUCH different documentary without the Crockett brothers being interviewed. It was interesting how different they were: Jim put most of it past him (but it was very weird he pretended his '93-'95 run didn't exist) and felt like the definitive authority, David was still bitter (similar to how he was in WWE's WCW doc) but provided good insight as well, and Jackie was not only not bitter, but had the most well rounded viewpoint since he's clearly the biggest wrestling fan and stuck with WCW through the end.
The post-production is far inferior to say, Barbed Wire City, even though so much of BWC was shot old older equipment. I absolutely hated the artificial blur/faux soft focus that was on all of the talking heads (except Valiant for some reason), the blown up low res photos, etc.
