Dolphin Tale 2 is not a completely true story. It takes some inspiration from real dolphin conservation efforts and stories, but the plot and characters are largely fictionalized to make for an engaging movie experience.
Sure is. The movie takes cues from actual happenings and showcases the struggles and triumphs of the dolphins in a real-world context. However, some artistic liberties might have been taken to make the story more engaging for the audience.
Dolphin Tale isn't non-fiction. It's a fabricated story that aims to entertain and touch the hearts of the audience through its imaginative plot and characters related to dolphins.
