I agree with what Steph said. Romance, like a lot of genres, tends to follow a certain formula, and there are only so many basic premises. Boy meets girl, love triangles, love/hate relationships, on-again-off-again relationships, opposites attract, two people from different worlds falling in love, star-crossed lovers, the forbidden romance, the summer romance, the whirlwind romance, love at first sight, good girl falls for bad boy, rich girl falls for poor boy, old cougar falls for young stud, etc. etc. etc. It's all been done before, but what sets one story apart from the next are the characters and the situation they're in. A talented writer can take an overdone storyline and revitalize it by creating fresh characters, putting them in interesting scenarios, and telling their story in an engaging way. That makes it easier to look past the cliches.
