I finished the second season of Chilling Adventures of Sabrina. It was as good, if not better, than the first. It's interesting to see that while in general series are getting bigger and bigger with huge budgets, this show is so small in scale. There are only a handful of rather small sets (that are beautifully lit and decorated, and very atmospheric), and also the regular cast is not huge. Also while there are some special effects, it doesn't rely on them heavily. So it all comes down to the cast and storytelling - and when done well that's all you need for a compelling series in the end. You can have lots of money, but if those two elements aren't working, you still got nothing.
The cast are all very good and charismatic. Michelle Gomez, who was of course Missy on Doctor Who, feels much more at home here - there is something a bit witchy about her. Miranda Otto, playing Sabrina's aunt Zelda, reminds me a lot of the stone-cold, harsh characters Piper Laurie played regularly in titles like Carrie, Twin Peaks and Trauma.
Apart from Bronson Pinchot (who was only in the first season), William B. Davis (best known as the cigarette smoking man on X-files) and Alexis Denisof (probably best known as Wesley on Buffy and Angel) the others are fairly unknown, but very well cast.
Also it is absolutely filled with references to pop culture, not only in terms of posters, paintings (there are a lot of Clive Barker paintings) and parts of sets (there are doors and a skylight inspired by Suspiria), but also in the way some scenes play out: Gomez' character takes a strange man home, the man needs to pee and goes to the toilet, Gomez hits him with a hammer. Sound familiar?
Another episode plays a bit like Invasion of the Body Snatchers.
While you could be inclined to think the show is like Buffy (my own all-time favourite tv-show), it doesn't feel very similar to me to that. It's its own thing, but if anything I would compare it most with Harry Potter - a kind of satanic, witchy Harry Potter though.
