It's hard to imagine there was much clamoring for a sequel to "Dolphin Tale." The first film was a modest early fall success back in 2011, but even then, the story of Winter the dolphin was already fairly thin dramatic material, serving as little more than a nice pleasant aside. Still, somebody thought it was a good idea to head back to the well, and surprisingly - judging from "Dolphin Tale 2" - that person wasn't wrong.
