So supposedly this entire town is a dedicated sanctuary for witches, has been for generations, and only... one witch lives there? Huh?
In this alternate reality witchcraft is an accepted fact, yet it's not clear how exactly this town is any kind of "sanctuary" when there's plenty of witches living outside it who seem to be doing just fine, better than the one inside it actually. Plus, theres a disturbing number of townsfolk ready to start up the bonfires and dig out their dunking stools the first time someone whispers that witchcraft is to blame for any sort of tragedy.
I'm guessing that there's some kind of "bad" witchcraft at play making everyone behave this way, otherwise just about the entire town deserves whatever horrors come their way.
Sarah, the main witch, has no real moral backbone. She performs various spells to "help" friends, but lacking consent and with questionable outcomes. Some real "Harry Potter" love spell vibes here that we're supposed to be OK with. She keeps engaging in behaviors that are foolish at best, and life threatening at worst.
Her primary nemesis is delightfully evil in regard to their machinations and how they manipulate people. Best character on the show.
One episode left, that will determine how worthwhile the series is overall. Just slightly better than average so far.
