More fun? For who? It just isn't in our nature to be cruel.
Both of the dee's are writers (pre-pubbed, but still) and we understand the amount of work, blood, sweat and tears that go into writing a novel. So, if we don't like the book, we'll tell you, and we won't sugar coat. BUT, not liking a book is no excuse to belittle the author or all of their hard work. Sometimes we have very strong feelings of dislike for a book, and I'm sure that comes across just fine without resorting to nastiness.
