I just recently read a blog post about reviewer comments to a novel on the Amazon.com website. Apparently an author felt a reader's review was mean-spirited and had Amazon take down the review. I gather the reader really didn't enjoy the book. If that's all it takes to be considered mean-spirited than the movie critics shouldn't even have jobs. Come on people. Not everyone is going to enjoy everything you do. I mean scroll down my blog to my favorites movies and check out my "Garfield" spot. A lot of people thought that movie stunk, but as I said I personally loved it. In the end it all comes down to taste and asking someone to pull a review because of that is to me a form of censorship.
People should have the right to say what they think of what you have done. As long as they are not insulting you as a person or using vulgar language, they should have the riht to express themselves. One of my favorite authors, Mary Janice Davidson does a great vampire series. Her "Undead" series. I love this series but I have to admit that her third book in the series disappointed me. Did I stop reading because of that? NOOOOO. I just won't reread that particular book. But I know from reviews a lot of people did like that book in the series. It all comes down to personal taste.
So stop crying in your notebooks authors. You are never going to make every single reader happy. That's unrealistic. Be thankful for those who do love what you wrote and just shrug offf the critics. And for heaven's sake, don't have their reviews dropped just because they didn't like what you wrote. Get a backbone people.
