The story may be somewhat implausible. I remember making a time line of the plot once and the entire story takes place in less than a week. They are married to each other in less than three days. They really only have actual contact for a few days and yet they commit suicide over one another. However, what makes this play so special isn't the story itself, it's the language. The poetry used throughout almost every single scene is simply breath taking. It's not the profound soliloquies of Hamlet or the word play of some of his comedies, but more innocent, endearing, and bittersweet. The balcony scene, when she waits for him in her bedchamber, when they depart, and of course when he finds her in the tomb...all AMAZING writing. That is, of course, why we love Shakespeare; and that is why Romeo and Juliet is special, not because it is "the greatest love story ever told." (Because West Side Story was stupid....)
