Do you ever get reviewer's block? I find that when I am reviewing a middle-of-the-road book I have a hard time coming up with things to say. When I love a book, I don't have any problems coming up with my review. When I hate a book, I have lots to say about why I didn't like it. But when I feel ambivalent about a book, or like it just "okay," I can't ever think of much to say.
Does this ever happen to you? What do you do when you are short on words?
