The kids watched both of the new documentaries and both kept them quiet but this one for me was just beautiful, I knew somethings about dolphins as I'm an Attenborough devotee but this was informative and beautifully shot. The narrator hit the spot nicely unlike the the other one I watched which was irksome and wondered why the had not chosen a man to do it. The film action was not something I had seen before and it held my attention and the kids loved it.
