Besides Belle, Ariel is my favorite Disney girl. I haven't seen this show for a while, but I remember loving it. But because of Disney XD replacing Toon Disney, I'm not sure where you can watch this other than online.
I liked the series (Toon Disney is off-air now). But, even though this is a prequel to the movie, some things happens earlier before it did in the movie (for example, Ariel normally encounters Ursula but in the movie she just met her.) There is some mild violence, mainly peril and scary-looking villians). Ariel's outfit is a bit suggestive. Not much to worry about.
even though most little girls love the little mermaid it isnt as friendly as it looks. there's lots of vilonce and peril. also Aerils costume is completly inapropreat for toddlers. but along there way there is apropreat content and positive messages too.
My kids are not really taken by this show. If fact it can scare my 5 year old daughter. The magic, threat and perilous scenes are a bit much. If you have a little one that is easily scared, aviod this even tho it has a sweet mermaid character. If we watch this I TIVO specific episode and pre-watch.
