Especially when they get things wrong. The Upside-Down isn't the plane of darkness, that's the Shadowfell or the Demiplane of Dread. You don't roll to attack with Fireball. You don't use Shadow Walk to travel between planes, you use Plane Shift or Gate. Eleven isn't a mage, she's a psionic at best. Demogorgon is a person. I am not "the Ben," there's not an admin here named "the Hassknecht," the lord of the underworld isn't the Lucifer, and the Greek god of the sea isn't the Poseidon. And for Christ's sake, you don't use Fireball against a friggin' demon. Almost all of them are immune to fire.
