One Fish Two Fish Blackfish Blue Fish
I highly recommend the documentary Blackfish, which focuses on the dangers of keeping killer whales in captivity (especially one particularly large and incorrigibly uncontrollable whale: Tilikum) and my wife and kids loved it too, but I should warn you to strap yourself in, as there are some graphic moments: you see some footage of the attacks (and seventy killer whale attacks have been documented, all of them occurring when the whales were in captivity), including the recent one where Dawn Brancheau is killed (but while director Gabriela Cowperwaithe allows you to witness more than Werner Herzog does in Grizzly Man, the footage is just to get an idea of what the whales are capable of, and stops short of being a gratuitous snuff film) and you will also see a killer whale penis-- my son Ian commented: "that wiener is bigger than me"-- and learn about the killer whale version of impotence (male dorsal fin collapse) and while my son Alex's review of the film was flawless: "epic but scary," my younger son said the movie was "awesome" but he only gave it "four and a half stars" because "it was missing something" and it turned out that what he thought was missing was "really good" footage of the attacks . . . but once my wife and I explained to him that these were real people that died, and that their friends and family might be watching the movie, then he understood why they didn't show the entirety of the violent scenes; this film is eye-opening and compelling, and it will certainly make you rethink your trip to SeaWorld (or the ersatz Canadian version, SeaLand).
