1. The Cove
Site rank 7, IMDb rank 11; Overall Score = 18
Directed by Louie Psihoyos
Not many films have causes as much public outcry as The Cove. That is one of the reasons it tops our list of 11 best environmental documentaries on Netflix streaming in 2015. It took techniques that are usually seen in Bond movies to document the truth behind the Taiji dolphin drive hunt. In a small inaccessible cove, local fishermen herd the migrating dolphins and kill them in the cruelest possible ways. The horrors that happened in Taiji and elsewhere in Japan claim the lives of 23,000 dolphins every year. The cove in question is well protected with barbed wire and guards and access is limited. Yet the crew managed to infiltrate it and film the gruesome scenes that shocked the world. The film won an Oscar for Best Documentary in 2010 as well as the Audience Award at Sundance.
