I think that ballet stories just get in the way. They are at best trite, at worst insulting in their simplicity and stupidity. What is the "story" of Beethoven's 5th symphony? I presume you think that great music can stand on its own. Why not dance.

The wonder of ballet is not the telling of a simplistic story but the beautiful, evocotive, enthralling, captivating, exhilarating, athletic, mesmerizing, movement of the human body to great music. I list Agon as one of the greatest masterpieces in the history of mankind. I can't imagine a story ballet that has anywhere near its power. It is the essence of ballet. It is just magnificent. Words cannot describe it. It has to be seen in person with great dancers, good musicians, and rapt attention to comprehend its power.
If you go to see a ballet performance to enjoy a story, you are mostly missing the point of it all IMHO. Most comic books have better stories and are a lot cheaper and are faster to read. By removing the simplistic story from the ballet, it is not lessened but greatly enhanced if done well. There is nothing to distract from the power of the dancing and the music.
If I thought I would never ever see Swan Lake, Giselle, et.al. again in my lifetime it would not phase me in the least. But if I thought I would never ever see Agon again it would break my hear. Fortunately, I have tickets for it this coming season.
My most humble opinion.
