“The Little Mermaid” (*1/2 out of four) was a trashy adult adaptation of Hans Christian Anderson’s classic story about a young mermaid (Rosie Mac) leaving the sea for the human world she thinks she is ready for but she must face the harsh realities of the world and street life, especially when she discovers sex and becomes a stripper! For anyone who loved the 1989 Disney classic, it’s bewildering; for anyone else, it’s unpleasant and boring. Hard to believe Christian Anderson would want his name on this. This makes the recent live-action “Beauty And The Beast” look like Oscar material.
