Don't watch this one for the acting (wooden, for the most part), or the plot (entirely predictable), or the pretend violin-playing (wretched). Watch it if you love DANCE! The dance sequences of the genres represented in the film are beautiful and, during their best moments, mesmerizing. The final competition piece is utterly tremendous and the one surprise of the movie - it was so much better than I expected and perfectly married the different dance styles in tension throughout the rest of the film. Dirty Dancing, Swing Kids (1993), etc - I love dance movies with real, authentic, talented dancers or even actors who have found their groove just for the movie. They are true artists that celebrate the sheer joy and raw beauty of dancing in all its forms.
(OK, I'm jealous - I could never do even one of these moves. Just saying. But I do love to watch people who can!)
