In writing, the Holy Grail is a five star review.  We all want them, crave the warm glow those five little stars brings.  But I'm only interested if they're genuinely given. I was searching groups of Goodreads when I came across a group that were all about reading and reviewing other author's works.  Great I thought, so I joined.  It was only then I saw the post from the group facilitator, basically saying that they were only interested in five star reviews, so if you were reading a book and couldn't give it a five star, then stop reading it and find something else to read. I love five star reviews as much as the next person, but that approach is completely wrong in my opinion.  If I get a review I want it to be genuine, if someone reads my work and thinks it deserves three stars, then they should give it three stars, and if possible write a review so as an author I can understand what it was they didn't like.  Filtering the results so authors only get five stars is no good to anyone.  It gives people an inflated opinion of their work, look at me I only have five stars, and it potentially tricks people into reading a book they normally wouldn't. So I left the group straight away.  Feedback is essential in this game, but you have to have thick enough skin to take the good with the bad.  Otherwise you're in the wrong profession.
