Torchwood - Countrycide.
The 6th episode of the first series abandons sci-fi completely and goes for visceral horror of the backwoods butchering variety.
The Texas Chainsaw Massacre relocated to the Brecon Beacons.
Written by Chris Chibnall (
Doctor Who /
Broadchurch) this is gripping, brutal and tense viewing.
Countrycide is horror the likes of which is generally avoided by British tv makers.
