I am or at least was a ballroom dancer. Thus watched this movie long time ago, still have the DVD. It cheers me up.
The male lead was a theatrical artist therefore felt short at the flexibility department of ballroom; but really liked Moon, beautiful dancer and very persuasive actress indeed.
I'm everything about great music of a movie. Sometimes more important than the movie itself. Right moment right music is like a key. I would watch a movie because of the music and still think the movie is great even if it sucks.
If I did have thousand of years, I would still love to dance. :)
