Booking Through Thursday: Writing or Riveting?

This week's Booking Through Thursday asks...

Writing or Riveting? What is more important. Good writing? Or a good story? (Of course a book should have both, but....)

I think I'm going to have to go with a good story, because if the story has my full attention I won't pay much attention if the writing is not so great. If the story was not good, even if the writing is great, I think it would be hard for me to get through. 

What is more important to you??
