I've seen a lot of information about Orcas away from Blackfish, though that film is the trigger that inspired me to research more.
The captive breeding programs aren't there for conservation, they're in place to keep the industry and entertainment going. Yes, seeing one up close is very inspiring. The problem is that we can't viably keep them living happy and full lives in captivity. It's basically like shoving a human into a twenty by twenty room for their entire life. You'll have one bored, frustrated, upset person.
