Prior to reading a book I WANT to read, I will look to see how many 5 stars and how many 1 stars there are, but I won't read them. If I'm trying to make up my mind about a book, or if I've just finished it, I'll read both 5 star and 1 star reviews to get both views. I never bother with 2, 3, or 4 stars. I only care if you REALLY love it or REALLY hate it
