I know we all have different opinions on what makes for a good review, and there have been a few club posts about writing good reviews, but I want to know what makes a review useful to you as a potential reader. What elements in a review do you pay most attention to? What can sway you one way or the other with a book? What do you wish more reviews included - or excluded?

If I'm writing a review for other people to read and judge the book on, I want to make sure I've included what people actually care about!
