It was one of the hottest films out of the Sundance Film Festival, but "Blackfish" will leave you with chills. Critics have praised "Blackfish" for being an "emotionally powerful" and "mesmerizing psychological thriller" that could double as a teaching tool. Thank you for watching CNN Films' documentary "Blackfish" for more information, please visit cnn.com/blackfish.
To put a huge orca in a tiny pool and keep it there for years, all the while making it perform tricks for frozen fish is so cruel in and of itself that it should be outlawed. You cannot justify the treatment by saying there is some good coming out if this. The ends never justify the means. SeaWorld does do some great rehabbing, and they get cudos for that, but large mammals which are possibly as intelligent as humans do not belong in captivity. We need to empty the tanks now. #Blackfish
