Blackfish

This is a 2013 documentary directed by Gabriela Cowperthwaite about a captive killer whale named Tilikum. This whale has been captive in sea world and is known for having killed a number of different people.

What I liked about this documentary was that it really tried to take its time with describing the circumstances of Tilikum and the industry of sea parks. It clearly has a firm stance on how captivity is wrong and how these animals should be free, but it does a great job of showcasing why these events happened in the first place and how the trainers themselves always had the best of intentions.

This documentary best fits under the category of expository as it has a major focus on the verbal commentary of the people telling their personal stories, as well as the news coverage and behind the scenes of what had happened.
