I'm part of the Student Animal Alliance at my university and we are getting together to see this. But in high school my best friend and I watched "The Cove" and decided then and there we were NEVER going back to SeaWorld unless it was to burn it down (after all the animals were removed safely, of course).
But in all seriousness, you bring up a valid point. Giant animals meant to roam and hunt in the vast oceans of the world being captured and trapped within, to them, what is hardly more than a water-filled cage... Is so wrong. The fact that people expect these predators to then become docile show creatures? Even worse.
