In your opinion are Romeo & Juliet greatest love story ever?

No.

In my opinion, Romeo and Juliet isn't even a love story - it's a lust story. They married only after knowing each other a day and a half, they were obsessed with each other and their relationship was downright unhealthy. Not to mention Romeo wouldn't have given Juliet a second glance if she wasn't pretty; they're only attracted to each other because of their looks. Ever notice how, when Romeo ever spoke to or about Juliet, it was always about how beautiful she was and never about her personality?

The good news is, Shakespeare purposely made it that way. Shakespeare did not think this play was the greatest love story ever; he was demonstrating what an unhealthy relationship was like. His moral was clear: nothing good can happen when you become obsessed with another person. He was trying to make a point with this story.
