Blackfish Documentary

So I downloaded this documentary about killer whales last night called Blackfish.  It was pretty good but after watching the trailer, I was anticipating some rare, unknown footage of attacks that SeaWorld wasn't able to snuff out and/or buy from frightened onlookers.  Nope.  I'm usually not this blood thirsty, but no gore whatsoever wasn't what I signed up for.  They told stories of a bum jumping in and losing his genitals, with trainers being bludgeoned against walls and others being dragged around like ragdolls.  Nothing more than the trailer.  At least The Cove delivered in the end.  Enjoy.
