This was the best film I saw at the Haifa Film Festival.
It is a "rotoscoped" movie, which means that it looks roughly like a moving painting. However this was accomplished, it is stunning to look at. Apparently it is based on an old Chinese folktale, but it's basically Cinderella set in Chinatown in New York City. However, despite the familiarity of the story, it is emotionally very powerful and had many in the audience in tears, myself included. The music in particular is very beautiful. It also does not shy from sexual issues and has moments of horror as well - not really for kids.
I recommend it highly as a unique film experience that many will appreciate.
