Blackfish

Blackfish single-handedly tanked SeaWorld's stock by 33% and ended their orca breeding program, a destruction that outperforms #7 in corporate damage. Gabriela Cowperthwaite's 2013 film about captive orca Tilikum, who killed three people, led to a 60% drop in attendance and widespread concert cancellations. This documentary is 50% more effective than the average exposé, measurably destroying an industry rather than just reporting abuse.
