Call me weird, but I read one star ratings before choosing a book to read from Amazon. Some authors complain that competitor authors troll and leave bad reviews. I have no idea about that, but I find the brutally honest one star reviews point out characterization and plot flaws. With the bad side pointed out, I move up the star ladder. By the time I read the last two five star reviews, I know if I’m buying. As a newby writer, I pay attention to the one star complaints in order to learn what works and doesn’t work, from other picky readers.
