I agree that “This blew me away” is pretty much of a non-starter when it comes to class discussion of a novel (or a short story, or a poem), but I would argue it’s still the beating heart of fiction. “This blew me away” is what every reader wants to say when he closes a book, isn’t it? And isn’t it exactly the sort of experience most writers want to provide?
