I am a little bit ashamed to say that a woman older than 40 told me about her, even though this song has appeared on Glee, and I am a Gleek. I enjoyed the dancing the most, if you watch close to the end when the male lead is pulling back all the females, my breath caught because this is what dancing is about. All those shows, such as "So you think you can dance", have almost cheapified dancing for me, because they do not tell the viewers i.e. voters the criteria or characteristics of a good dancer...its not just about likability or beauty or political correctness. Instead, any critism from the judges, which will help imprive the constestants dancing is "booed" by an uneducated audience. Its not just about the lines, emotions, its about a story. Its acting except not with your voice, and body and emotions, but with movement as well.
