This is a typical 'hot button' issue. Most people refuse to even try to see both sides but seeing both sides is necessary.
Would I prefer Orca's not be in captivity? Certainly. But these that are left are nearly all captive bred and simply cannot be released. Further, with only 50+/- Orca's in captivity in the ENTIRE WORLD, this is really a small story. Far, far greater animal abuses exist and demand our attention and action in the world (the annual whale slaughter, poaching, big game hunting, caged big game hunting here in the US, etc). Yet these issues remain ongoing with little hue and cry. IMO, the biggest issue to mull here with regard to SW is should they and others be allowed to breed Orca's.
The outrage over the Orca seems to center around their perceived intelligence but where is the outrage for the gorilla or elephants? Both intelligent and social. Why is it OK to train dogs but not Orca's? The Orca's at SW don't "seem" sad but these so called experts tell us they must be. Are trained dogs sad too? Do we care or are they just too dumb to care about?
Where is the line drawn?
I totally and unequivocally condem the past tactics SW used to capture these animals but that was long ago and many owners ago and capturing wild Orca's IS NOW ILLEGAL, a move I applaud!
SW does a lot of good for the animal world even while being a rich, for profit company. Their initiatives and aid of manatee's is probably one of the main reasons we still have these lovely, gentle creatures.
With regard to zoo's in general, I am all for as natural environment as possible but the fact is without zoo's we will NEVER see many extinct and soon to be extinct species (the black rhino has now been listed extinct in the wild). Is keeping these animals alive in preserves and zoos really worse than outright extinction?
Blackfish was stark, unsettling and terribly sad but not very even handed. SW, a big for profit corporation with many skeleton's in their closet is hard to feel compassion for despite their offsetting high marks in other animal care areas. So they were an easy target but I would have preferred the filmaker's time, efforts and money aimed at bigger fish, so to speak.
