In 2013, documentary "Blackfish" was released. And SeaWorld — or, more specifically, our perceptions of SeaWorld — changed forever.
The film explored the life of Tilikum, an orca (killer whale) living at SeaWorld Orlando that's been involved in three separate human deaths — in 1991, 1999, and 2010. While the knee-jerk reaction may be to cast blame on an unruly, dangerous orca, just the opposite is true: It was Tilikum's years in captivity that resulted in his hostility.
