You know, Allyson, I felt exactly the same way about Margaret Atwood at your age. Then in the last ten years or so, I *got* her. All the relationships she wrote about, the dark humour, the irony, all the things I hated about her writing when I was younger suddenly clicked. I can even understand her public persona and demeanor. She doesn't take herself at all seriously and I think what appears to be pretentiousness is her rather dry, sardonic sense of humour.
Don't force yourself to like her now - out of a sense of duty - but give her another try in about ten years. You might be surprised.
