Struggling against saving Winter, Dr Clay Hasket and his team of brilliants, who go on a mission three years ago to save Winter, now, after the death of her mother, Tamara, has died, the thing that challenges her, so the team goes in another mission to save her.
Some angst away from the dolphin tank feels like padding, but there's enough bona fide narrative to please tomorrow's marine biologists and their parents.
You know how this ends, right? Of course you know how this ends. So the point of the film isn't the foregone conclusion, but the journey, which is... bland.
