I watched this movie as I wanted to complete the Roxy Hunter series. I was highly disappointed that the amnesiac mermaid girl Annie didn't speak :(. I really wanted to hear her speak. There was also not as many mermaid scenes as I hoped as this is a mermaid movie after all. younger kids will need to know about amnesia to understand about the mermaid charcter so I think kids ages 9 and up will enjoy this movie especially tweens.
