Am I the only person who hasn't read the Steig Larsson trilogy? I haven't because I've heard they're extremely violent, and I don't like reading violence. But my avoidance doesn't seem to have made much of a dent in their popularity. I've not read much misery lit either, or science fiction, and even in genres I do read I have big gaps.
One writer I like reading is Anne Tyler. My least favourite book of hers is Breathing Lessons. It won the Pulitzer Prize for Fiction in 1989, so obviously they didn't feel the same as me.
I once brought into class the opening scene to Ian McEwan's Enduring Love, as an example of writing a compelling suspense-filled beginning. Most people agreed but it wasn't a 100% success - one person said they'd got fed up with all the hinting and would have stopped reading.
Three examples where different people have different reactions to books. All the books have been hugely successful, all have their detractors. The book that everyone loves is as rare as...well, a unicorn.
So feedback has to be taken with a pinch of salt, as does any prescription or formula for writing. There isn't some perfect standard that we're all aiming for, a universal book. There is only the best book that you can write at this time (which may be quite different from the book that you write next year, or the year after that).
