This film completely changed my perception of orcas in captivity. While it is important to note that the film IS propaganda, the question of validity remains. The film presents an excellent opportunity to teach our kids to think for themselves, and not to be manipulated by the media. It's a great conversation starter for tweens and teens, in which parents can encourage them to question information presented to them as factual. Just because it's a "documentary", doesn't necessarily make it true. Parents and kids can easily research both sides of the story (Sea World's response is on their website, as well as a follow-up on www.blackfishmovie.com) and come to their own conclusions. I, personally, am deeply saddened by the false impressions I previously held of happy, healthy orcas in captivity. The evidence presented in Blackfish is undeniable, from their collapsed dorsal fins to their scarred-up skin. Decide for yourselves!
