We bet you didn’t expect a documentary about racehorse to be on our list of 11 best nature documentaries on Amazon Prime. For those of you unfamiliar with the sport, horses are just as famous in the horse racing as the people who ride them. This is a story about Frankel, one of the most appreciated racing horses in the history of the sport and arguably the best one that competed in the 21st century. The documentary follows the unique partnership that Frankel and Sir Henry Cecil (thought to be one of the best horse trainers ever) developed and how Frankel’s success cemented Sir Cecil’s place in the history of the sport.
