Went in as an Ella Purnell mega-fan and was ready to eat up just about any breadcrumbs tossed my way but ended up liking it for completely different reasons.
Everything from concept to vibe to performance is solid. Not many shows can get me to like nearly every side character on screen and this one does it. The little office set-up was brilliant, definitely an atypical spin on the serial killer/slasher genre. Keep in mind you're supposed to feel deceived once you realize the protagonist is relatable but unhinged because guess what, THEY KILL PEOPLE and they did it in the first episode!
Loved it. Hope it picks up so we'll get a second season.
