Why is the quality of Stephen King's novels decreasing?

Because Stephen King is getting very old, and, actually, most of his books were never terribly good, anyway. He was a very good advertising executive, hard working and creative, but, this meant that he was always trying to appeal to the lowest common denominator. And, that’s what his books have always done, too. He’s always been trying to make as much money as he possibly could, by appealing to fairly illiterate people, with rather illiterate books. Personally, I think Stephen King should have stuck to advertising, that’s really what he was born to do. He wouldn’t look quite as ridiculous as he does today, trying to pump out horror shlock to make money, when he’s too old to have any new ideas. Old writers can still be very good, and can even improve with age, if they’re really good writers, who are fascinated by human nature, and forever curious. That’s not Stephen King! He’s just a greedy SOB who is always working frantically to make money. You know what the true “horror” is in Stephen King’s books?
