Great historical information but then it seemed like the documentary was half finished. Technically there were spots of bad audio on a couple of the subjects, from using either a shotgun mic or on camera mic which allowed background noise in. There were also some subjects that were shot with either a different camera or a new shooter jumped in and didnt white balance or set up camera properly. Then the music was half n half where if the film makers stuck with orchestration, it would have worked but then they switched to music by Spiritualized and Ivy? These are great musicians but it didn't work with the documentary. It has it's moments but it wasn't spactacular. If you're a sword lover definitely watch it.
