One of the most talked about documentaries of 2013 remains director Gabriela Cowperthwaite's Blackfish: a horrific look at the maintenance and care that goes into taking care of the orca whales at various sea parks. Throughout the decades, these majestic creatures have inspired awe and splashed their share of audiences. Yet there is an even more haunting truth behind these performing sea life animals. They aren't always the friendliest of creatures and rarely kill their trainers. It is a horrific truth that becomes the center of one of the strongest documentaries of the year.
