I think that two things are being confused. Good quality writing and a good book ...
I am NO literary reader I admit that from the off. Sometimes I am a bit embarrassed by some of the stuff that I really enjoy
But last year I read two books by Tom Clancy. HUGE sellers. OMG people, the writing is atrocious ! to get through it I had to go into a kind of suspended belief state.
However .... the story takes over. His story telling is so magnetic, so involving that you forget the writing is so $hite.
Now after the second book I drew a line and decided no ... no more. BUT I do accept that he writes great stories and people love them and his books deserve to valued as great books. Just not great writing.
