Sure, I'd be glad to tell you why I can't stand Nora Roberts. But don't say I didn't warn you!
Sorry in advance to any Nora Roberts fans or any romance fans in general.
I read a collection of some of her stories a little while back, and I was absolutely disgusted with it. Nora Roberts is quite a famous author who has millions of fans who adore her work for the same reason I despise it.
In each of the stories I read, a sensible girl (usually a virgin) meets his stereotypical guy who in her world in the ideal man but in real life would probably be a mass murderer or rapist. They meet as indiferent acquaintances but then all of a sudden the lighting's right or something superficial like that and the girl (or guy - whichever one it is who isn't interested) realizes that they've been in love with the other their whole lives. So Person A gazes into Person B's eyes, they kiss... sorry, "his lips crushed hers..." and they get down to business, more often than not, an act that is in complete contradiction to Person A's moral standards. Up until they realize they love Person B, of course. Then, the next morning they get to know each other, then something tries to break them apart but it doesn't work, so they are still together and happy as clams.
The sad thing is that I know many, many girls who love to read romance novels and just eat up the morals in these books. I'm talking about the girls who fall in and out of love so fast it's like riding a rollercoaster. They've never found true happiness and they've never been truly happy with one particular guy. If you get them on a bad day, they'll admit that they don't even know what love is.
The other type is the girl who'se been madly in love with this one guy for maybe years now, but either she's too shy to let on, or he doesn't treat her well but she thinks that's normal. (Yes, people like this actually do exist. I know plenty of them!) They're too star-struck with the notion of love at first sight that they block out all the negative about the person until they don't know them all. In the end, they're in love with the body and name of their significant other, but they've created a personality for them in their day-dreams.
That's the reason I don't like Nora Roberts. Books like her make people wishy-washy and if you buy into it, it'll mess up your life. I realize this is pretty harsh, and I'm not trying to start a debate or anything. These are just my personal opinions.
