Disclaimer: Not an activist, not keen on PETA or other extremist animal rights organisations - just someone who tuned in because the documentary got a good write-up.
It is a gut-wrenching, heartbreaking look at orcas in captivity: intelligent, social animals who live in family groups they never leave, swim up to 100 miles a day, have a language unique to each pod and can live up to 80 years. Confined to bare concrete tanks, separated from their offspring and forced to do fucking tricks for dead fish before they die after half of their wild lifespan.
I know world hunger, Syria, FGM and plenty of other things are more important, but this truly is a stain on our species' already appalling record on animal treatment. And more to the point, it's very easily fixable.
Watch it - honestly it is haunting and shaming.
