Cuckoo is one of my favorite stories from the entire run of Torchwood. The new characters we're introduced to all feel like they could easily have had a prequel monthly audio I missed based on how much depth they all have. Billis is chilling and calm as always. I love all the callbacks to More Than This and Cardiff Unknown. 5/5 one of the poster stories for what Torchwood can be.

Bilis Manger is absolutely terrifying. It's a diversion from the main storyline of the season, but one absolutely worth it.
