Also why does everyone have to like WSS? That's like asking why everyone has to like Shakespeare, or the Beatles. Even if it's not your favorite or you do not personally enjoy it, you have to at least respect the talent behind it and admire the work for what it did for the art form.
To say that you find West Side Story dumb and, in fact, cannot find a single redeeming quality about it, does nothing but give the impression that you are very young and know NOTHING about the art form you say you love.
I can't stand Eugene O'Neill plays. I find them tedious to sit through and even more obnoxious to read. But I would never say that O'Neill is a hack or that THE ICEMAN COMETH is dumb.
There is a difference between a subjective reaction to a work, and an objective determination of quality and/or importance.
