What does it Mean to Call Something Romantic?

For English class, we are supposed to say what we think it means for something to be categorized as romantic.  For me, I don't believe that for something to be romantic, it has to be a mushy love story.  To be romantic just means to please something.  So if a painting is dull colored and ugly, then you could say that it isn't a very romantic painting.  I think that today's society views romantic as a certain idea, and that idea is love.  Even though it is its own category in literature and other works of art.
