Barbie Fairytopia is the fifth Barbie movie, and the first one to have a completely original story. It's not based on any particular folktale, ballet, or anything else, just generic fae folk fun. There is an evil sorceress, but this is the first movie where they didn't pay for a celebrity to voice the villain. Shame. In fact, they really limited how many voice actors they paid, half of them doubled up on roles.
Elina is a disabled fairy, who has no wings, and gets picked on, but she's the only one immune to the everyone with wings sickness the evil sorceress makes.
Her best friend/pet? is Bibble, a blue puffball that speaks babytalk jibberish. Bibble has a fanbase, but I'm not sure why.
There's no singing, and no real love interest, though the mermaid prince is a little creepy, but it's fine. He's not in the movie long.
In the end, evil sorceress turns to confetti, and the queen of the fairies gives Elina magical prosthetic wings. I dunno what kind of message that gives to disabled kids, but whatever, it's a Barbie movie, and they wanted the doll to have wings, obviously.
Was the movie good? It wasn't bad, and I was entertained for an hour and 10 minutes, and now I'm inspired to make fairy costumes for my Barbies. So yeah.
