Opening with a heart-stopping 2010 video of SeaWorld Orlando senior trainer Dawn Brancheau being dragged to her death by Tilikum, an orca known for killing before, Gabriela Cowperthwaite’s documentary “Blackfish” is enough to make anybody think twice about the wisdom of turning whales into performers. “Blackfish,” which had its world premiere at the Sundance Film Festival, relies on often-disturbing video shot by various park guests and trainers that shows orcas turning on staff in what experts in the film explain are not acts of aggression, but rather frustration at being held in, as one describes it, “a concrete bathtub.”
