Query: Billionaires don't make good writers!

J.K.R took too long to write this and the result feels like too long of a chapter in a longer book. With Harry and company reaching young adult ages, this book is neither a children's book nor adult, and excites neither. She is detached and void of passion as the writer, as are the characters and the reader. Everyone is shows up for work with a job to do, and perform roles in a sales and marketing venture and get done with it, making her and the HP moneymaking machine another round of gold. The experience is underwhelming and disappointing, quite a waste of time :-(
