With the
Cursed Child, J. K. Rowling has effectively destroyed the charm of a Harry Potter book. True, the fact that it is a play vs a novel does take away from the book. But even as a novel, it is clear to see that the book would have been half as interesting as the worst Harry Potter book. With lazy plotting, characterization, narrative flow, it is plain to see Rowling has descended to Chetan Bhagat's level.
The feeling I was left with at the end of the book was disgust at having enriched the already mega-rich Rowling again. The book did have its (rare) moments but for the most part, it is everything you do not expect a Harry Potter book to be.
