'Blackfish' was an excellent documentary, and I came away from it fully believing that we shouldn't hold orcas in captivity. A chilling (and fascinating) point in the movie is that when one of the orcas nearly kills a trainer, the killer whale doesn't bite or buffet the trainer, but instead holds him underwater to drown him.
