The Crimes of J.K. Rowling
I've been skeptical about the the plan to make five "Fantasic Beasts" from the beginning. Granted, the first one was quite decent. However there was no way J.K. could manage a quality storyline of the grand Harry Potter caliber again.
Well, as a surprise to no one... She didn't!
Her twitter ramblings, which frequently retcon character details, relationships and basically everything that isn't 100% PC anymore, already made it clear that she lost control.
