Yeah but the whole lesson of the story got completely changed!
Molly was best dancer in class, curled her hair to get the part, started getting cocky, ended up getting an ear infection and didn't perform at all.(yes I remember the book even though I read it almost 10 years ago lol)
Molly is the worst dancer in class, works hard, ends up getting the part and being the star at the performance.
The movie's message wasn't bad I guess but still they changed the entire story basically, and it's my favorite book of the series(obviously since I remember it perfectly lol)
I'm an Otaku and I'm DAMN proud of it!!!!!!!!
