This was a decent watch, not for cinematic reasons per se but for making the world a better place. I watched this with my son, Julian, and I was pleased with how they took the true story, including the actual dolphin from it, and, especially for kids, promoted environmentalism, caring for animals, etc.--really solid and important aspects that need to be, more than ever, emphasized in the youth of today.
My only qualms is that I have very mixed emotions about the casting. I know that to get an important environmental message heard, and thus the film watched, you have to incorporate Hollywood megastars. I simply wish this didn't have to be the case. The story would have come across better with unknown actors--or simply as a sincere documentary without the Hollywood B.S.
