Rereading a favorite book after ten years and liking different parts

I reread a book I adored ten years ago and found myself caring far less about the adventurous main character and much more about the exhausted supporting cast. The plot hadn't changed, but I apparently had. A few lines I once found profound now read as melodrama; other quiet passages stopped me completely. Have you had a reread that felt like meeting a different book rather than revisiting an old friend?
