My second favourite of the Barbie movies
26 May 2012 | by TheLittleSongbirdSee all my reviews

I admit I do enjoy most of the Barbie movies, though none are among my favourite movies. Of the lot, my personal favourite is Nutcracker, but Diamond Castle is my second favourite. The animation here is among the best-looking of any of the Barbie movies, colourful and wondrous. The music is very catchy, any movie does its job well if you remember or love the music, and while Nutcracker, Rapunzel and Swan Lake have music that is more to my personal taste, Diamond Castle does its job well indeed in this respect. The dialogue is good, not too corny, and the story is cute, has a lot of heart and while there is a dark centre it is not too dark. I love the characters, especially the twins and Slyder, and the voice work is solid from all, Kelly Sheridan and Scott McNeil impress me every time I hear them. In conclusion, I really like this movie, given a chance without prejudice you may like it too. 9/10 Bethany Cox
