Take Satanism and evil magic from medieval Christian superstition, rather than from Wicca or LaVeyan Satanism which don't believe in a real Satan. This is already a borderline hate crime.
Add bullshit high school drama and an anti-bullying, anti-transphobia plot that goes nowhere because nothing mortal matters. And it's weird: Everything in the show tries to look like the 1960s, but with random modern anachronisms. I think the writers and set decorators are not being clever here, they're just too stupid to understand how different the 1960s were.
Add bullshit boarding school, half-blood bigotry from Harry Potter. The Harry Potter fanficcery is strong in this, right up to the suggested shopping for familiars, and witch girls with black lipstick who might as well draw "SLYTHERIN" on their foreheads.
Add one very dark-haired bleach-blonde-but-gross-roots-showing weird-looking chick who does a lot of shower scenes for someone supposed to be 16 (actually 19). Her creepy, lumpy boyfriend (actually 23, and looks 25+) doesn't help.
Add maybe the worst Q&A with a "High Priest of Satan" ever (imitating Lucius Malfoy, but with all the charm of a bored accountant).
The dialogue's awful, like a Christian trying to write "spooky gothic". It's exactly like fucking Twilight.
I made it barely into E2, and gave up. This is the worst.
