Just a millisecond or two after the cast of Harry Potter and the Cursed Child was unveiled on Sunday night, the Twitter-delivered criticism immediately caught fire. Some diehard Potter heads aren’t exactly stoked on the fact that Ron appears to have abandoned his confident red hair, while others are unsettlingly concerned with the new Harry’s general demeanor.

Others, amazingly enough, appear to be confused as to what exactly a "play" really is:

Set nearly 20 years after the events of Harry Potter and the Deathly Hallows, the trio at the center of Cursed Child includes Jamie Parker (Harry), Noma Dumezweni (Hermione), and Paul Thornley (Ron). Though Cursed Child is the eighth Harry Potter franchise entry, the play marks the first official Harry Potter story to debut on the stage. The story itself, of course, centers on the burden of the Potter family legacy in the face of the past's unfortunate tendency to occasionally collide with the present.

For reasons not immediately understood, a small army of dummies expressed immediate disapproval at the idea of a black Hermione, even though it's the year 2015 and such criticism sounds (and is) downright ludicrous:

Thankfully, Harry Potter mastermind J.K. Rowling isn't having any of that:

Harry Potter and the Cursed Child opens at the Palace Theatre in London in July 2016, with or without the unneeded approval of these dummies.
