This is a lengthy video, but I think it is worth watching if you have the time.
Melina talks about how being nice in reviews just for the sake of being nice is not the way to go. And I agree. I think authors all need criticism in order to learn and grow. Not everyone is going to love your book. That's impossible. Everyone is raised differently and has different opinions on things.
Reviewers review so they give other readers a perspective on what the book they may buy would be like. If you are a regular follower, you know that I give my honest opinion on every book I read and review. I don't feel that I should be nice in every review because hey, time is lost for having the book read and I don't get paid at all. Therefore I should have my own opinion on whether I like the book or not.
I want to hear your opinions as a reader and/or reviewer.
