I must say this doc is slow to the point, but it offers a truly inside look at this, almost entirely from first hand accounts. The music was great, with a great score, and soundtrack with some unexpected tunes from bands you know. One thing that this doc did right was the fact that they never broke the aspect ratio, as in they kept everything in 16:9 or relative, instead of going full Wes Anderson with the true aspect ratios of the different sets of film used over the years. In other words, they never broke the black bars at the top and bottom of the screen. This detail might not seem important, but it helped maintain the immersion and once I noticed I couldn't help but appreciate the tricks they used to make it work. Great editing, and a film that takes its time. It lets most of the anecdotes breathe and be felt with proper impact, and it did not feel like they were manipulating the testimonies for any sort of rhetoric or agenda, other than to take a very deep inside look into the strange minds of men.
