The Barbie movies are surprisingly good for what you'd expect. The graphics are simple, but there are actual stories that make it worth buying. The songs tend to be excellent. My daughters insisted I buy the sequel.
This story is about a girl (Merliah) raised by her grandfather who discovers she's half-mermaid on her sixteenth birthday. It turns out that her mermaid aunt has been keeping her mother prisoner, and Merliah has to rescue her and come to terms with her mermaid heritage. It's kitsch, but it's decent kitsch and my daughters adore it.
I have way more of these Barbie movies than I ever wanted, but it's worth the inexpensive price.
This is one of the movies that I can sit down with my three year old and actually watch from start to finish. My daughter LOVES the songs and we always dance along to them. Along with the great songs, the animation is great and the movie is sweet. Having a little girl that is obsessed with Mermaid and Barbies this was a must buy! You won't be disappointed!
