Top-notch documentary. Usain, his parents and his entire entourage present extremely well. Hey, so does the entire Jamaican fan-base. There are a few lines in this that succinctly explain why Usain was maybe the most popular athlete in the world during the latter half of his career. I won't repeat them. You'll see. The only issue I could raise is it should have included more info about the field he raced against in the Olympic finals. I know it is about Bolt, but that is important. Also, there were a couple of people in Bolt's everyday life who were never introduced, but somehow Serena was there over and over again.
I guess many people were bored because it doesn't try to create controversy, which is how Usain lived his athletic career.
