My goodness, many of you are so hung up on this movie. Forget the movie ever existed and we are left with one simple fact: large intelligent mammals are being held in very small concrete cells 60-90% of a 24hr period every day. Pretend the movie doesn't exist at all and this is an still an absolute fact, standing all by itself.
For those comparing other mammals in other facilities, relative size matters. If an elephant gets 5-10 acres or a giraffe 20-30, I feel confident they are reasonably happy and satisfied compared to those getting a concrete space 30'X40'.
The movie never existed. Above still holds as true and as fact.
