Directed by Gabriela Cowperthwaite.
This documentary has one goal, and it succeeds. It makes the case that orcas are friendly, social, emotional, non-violent creatures in the wild, but by capturing them and showing them off at waterparks, some of them are turning into killers.
The main focus is on Tilikum, a killer whale who's killed three people, and yet he still performs at Sea World. It chronicles his capture, and the three different deaths, and show how SeaWorld keeps downplaying the danger. In the end, it shows that orcas just don't belong in captivity.
