A Dolphin Tale the same way I feel about Invictus. The principle characters are so good-natured, so honorable in their intentions and kindhearted that it immediately made me think that the movie stretched the truth quite a bit. The characters are inspirational for their goodness, kind of like The Ultimate Gift and although the movie is rated PG, it can easily been mistaken for a G rated kids film.
Despite the obvious corniness of A Dolphin Tale, it is a corniness that works extremely well. These characters are so charming that we want to like them, and the dolphin Winter (playing herself) makes us want to root for her.
