Only for Ariel fans
The animation and music don't meet the standard of The Little Mermaid, or even of #2, Return to the Sea. The sisters are stereotypical femmes, fighting over mirror space, for example. The villain is really into fashion and wears wigs. Subtle stereotypes and Princess marketing aside, there's little cause for concern in this movie. But be aware that the mom's death and dad's (Triton's) depression, plus the electric eel minions of the villain could upset sensitive kids. The eels are introduced as scary, dangerous mystery creatures, kept in a cage. When you finally see them they're not that scary, but until then they are a bit dark.
