It seems to me many people will only ever rate a book, movie, game, whatever, if they reacted strongly to it, that is, if they either loved it or hated it. If they enjoyed it, then they’ll often award it a rating of five (out of five), whereas if not, just one out of five.
“Moby-Dick”, written by Herman Melville in 1851, has garnered its share of one-star ratings, and recently biblioklept posted a selection of ratings/reviews written by Amazon members who had read the novel.
I have seen better writing in a Hallmark card! Boring! Give me a good ole copy of Elvis and Me! A true story that really tugs at your heart strings! I sleep with that one under my pillow! Keep Moby Dick away from my bed!
