One of the key people interviewed is a whale researcher who testified in the successful suit against Seaworld (who incidentally is careful to say they can draw no certain conclusions from the attacks of the primary whale featured), and then trainers who worked and in a lot of cases witnessed the attacks. To be sure, Seaworld has often not been forthright, and often demonstrably lied, in a lot of important ways. That being said, there is also a strong appeal to emotion. Does not bother me at all and it is a good watch.
