What a great story. Maybe because it's a book adaptation, but it feels like very deep and developed story. Surprisingly even if Nyssa is the driving force of the plot, she's not having a big part in it, but Doctor and Tegan were absolutely amazing (as always). Gallifreyan lore and satanic panic fit perfectly and add much fun to the story. State of Decay always was one of my favourites, so it's nice to see some continuity here.

The cast was amazing and i really enjoyed the sound design and music.

Solid 4,5/5! And now I really want to read the book.
