I like the harlequins because you can read them in about 2 hours. But you are right, they are pretty similar. They hate each other but they are attracted to each other, they fall in love, misunderstanding, break-up, turning point, back in love.
I still enjoy them though.
I can't even get past the book jacket on the shades of grey trilogy though. Can you give a little insight without actually giving any spoilers so I can decide if I want to take the plunge on the trilogy or not?

Go to work, do your best, don't outsmart your common sense
Never let your prayin knees get lazy
And love like crazy"
