I'd watched this several weeks ago when SwordChick got her copy, and I enjoyed it very much. I'll echo everything Ed said above, particularly the comment about Paul Champagne (I knew Paul, so that was very touching to see him on film saying that he'll keep swinging a hammer until he dies).
I finally got around to buying my own copy, and I went ahead and got the two-disc set with the special features. There's the training segment in there that shows varius martial arts groups demonstrating techniques. While its neat to include this, I felt like the producers didn't give enough thought to who the audience was. There were several groups showing several arts, and most of the arts were not explained at all. There's one on Alfieri's plays... if you don't already study Italian rapier, then you would have no idea who Alfieri is. Further, most of the techniques demonstrated are fairly basic, meaning that if you DO already study Italian rapier and know who Alfieri is, then you probably won't get anything out of it. For the majority of the list of clips, they seemed to make the assumption that the viewer is already familiar with the WMA culture (at least for the WMA videos, anyway).
There's also a glitch in my DVD. The vid for Silver's Four Fights doesn't work (but I don't care that much, since I don't actually study or even like Silver's methods), and the vid showing the behind the scenes at the Higgins Museum also doesn't work (which bugged me more, because I wanted to see the swords!).
All in all, though, I'm happy with the main documentary.
