Dear Reader, 
It's always nice to hear from you. I have gotten some great ideas from readers and even took some advice and wrote an entire book in the Draoithe series for one of my beta readers.  Reviews of course are the best.
But what about bad reviews? I was looking at a book synopsis for an ebook that I was considering for purchase a few nights ago. (I don't personally buy books based on reviews but a lot of people do.) The book was on one of the five largest digital vendors (Not the big one.) 
The author was well known. I have purchased their works before. The book was one in a series that I have not yet begun to read so I decided to search for the first book in that series. (I love to read series books, but nothing is worse that starting in the middle to me. So the book in reference I did not purchase.)
But when I got to the end of the synopsis, the reviews were posted directly after. The second review caught my attention. It was unkind and disparaging. It lent nothing to any other reader and did not speak to the contents of the book. My immediate thought was 'troll'.  The reviewer was angry that the book was in a series and complained that it was not a book if it was part of a serial and felt ripped off.
I was stunned. Tolkien wrote the first fantasy genre books in series. Robert Jordan's wheel of time is a series. Felicity Heaton writes paranormal romance in series. Sometimes the story is just too big to fit in a single book.
After considering it further, I began to feel as if I had stumbled across a person who was used to and appreciated reading articles and not books. Some people prefer shorter reads. They can't appreciate getting lost in the pages of a truly good book and staying immersed in a world. So maybe I should not have mentally called the reviewer a 'troll'.
But I would like to note that a good book review should be constructive and kind. It is after all an opinion, but it should not intentionally inflict harm. One beta reader once told me that a whole chapter in one of my books needed to be rewritten because I had placed a character in two places at the same time. She was right. I was aggravated, but I rewrote the chapter. Had she told me she hated the book because it did not make good sense, I might have not caught the mistake. 
So lovely readers, please write reviews. But consider that kind constructive feedback is the best review for the author and your fellow readers. Negative hurtful comments are helpful to no one and routinely dismissed by the author and the readers. Most readers are very intelligent and see the disparaging uninformed reviews as disrespectful and unhelpful. If you honestly did not like the way a book was written or did not like the content explain why so that others will understand your review. 
Different is good. I would hope that we could all recognize that there are many types of authors and many types of readers. We all have a style we like, but a good review needs to be based on the contents of the book in question, not a dislike for a particular style of writing. Thanks for letting me vent.
Be Careful!
Happy Reading,
