As the musical Les Misérables wraps up a very successful revival at the Imperial Theatre it is with some sadness that we see it leave Broadway again. It feels as if this pop opera has been a staple of the Great White Way for decades. Perhaps that is because its original run was so prolific (6,680 performances) and this most-recent revival was nothing to sneeze at either (1,026 performances). The question is, just what is it about Les Misérables that keeps us going back, again and again, and what about it appeals so strongly to new generations? Why do we enjoy being "miserable"?
