It's a bit bad movie.
King Triton acted badly. He acted angrily in the whole movie. In this movie, Triton was always angry and behaved bad with his daughter. Also, Ursula told Ariel that she should get true love's kiss within three days. How can someone fall in love within three days? They can fall in love within months or a year.
In this movie, it is often very dark for most of the time. There was darkness in the sea, and that did not look nice.
Also, Prince Eric's skin was white, but his mother's skin was dark. Why don't they have the same skin? Eric's mother was Queen Selina. Eric had a white skin, so his mother should also have a white skin. I mean, a mother and son should look the same. Eric and his mother both have a different skin colour, so Selina doesn't look like Eric's mother.
Ariel and Eric got married at the end. In the wedding, Eric was wearing a white shirt and white pant. Is this what you should wear in a wedding? In a wedding, he should wear a beautiful dress or something special, not the normal white shirt.
I like the movie a little, but it's not my favourite movie. This is not a great movie.
