Black Dish movie review

So blackfish is a movie based on what SeaWorld does to killer whales and their punishments that they get. So Tilikum killed 4 people 3 trainers and 1 person that broke into his tank. So when Tilikum was at sealand he killed a girl that accidentally fell into the tank and drowning her while the other orcas were swimming in a circle. Blackfish also got people that use to work in SeaWorld to tell their stories of what SeaWorld did to the killer whales.
