Loving you was not part of my plan, and spending the afternoon/evening of 01/01/17 crying over your departure was definitely not what I had in mind...
Cursed Child leaks - and why writing that plot was a bad idea regardless of veracity
To be honest, that “leaked plot” could be an elaborate fake. But leaking a fake plot (after the premiere date, and thus, more likely to be believed true) is a ginormous financial risk. And one I don’t think was thought all the way through.
Harry Potter fans can be... enthusiastic. On the one hand they (sometimes we) will buy/promote/enjoy nearly anything Harry Potter related. Including ridiculously bad fanfic like My Immortal.
On the other hand... piss off the fandom and woe unto you. Pre-orders can be cancelled. Tickets can be hawked. Nostalgic love turns bitter and spiteful. And all that word-of-mouth money will dry up into cautious skepticism as those potential early purchasers decide instead to wait and watch and perhaps later change their minds that, even if the leaked plot isn’t true, do they really want to spend that much money?
Either way, troll story or true, writing the “leaked plot” of “The Cursed Child” online was a dick move. Not releasing it. No. Writing that steaming pile of internally inconsistent drivel and unleashing it upon the world. That was a dick move.
