I havent quite caught up with that yet Scum, but I have binge watched it this past week on I-Player and Im currently on the Series 4 episodes.
Shearsmith really plays the baddie well doesnt he, and most of the time Pemberton playes the more likeable one (although maybe not exactly a goodie).
I couldnt stop laughing today when watching the Hotel Zanzibar episode at the start of S4, and the bit where Shearsmith is about to kill somebody with his flick knife, he then gets hypnotised and starts doing the hokey cokey instead lol.
Superbly dark and farcical all at the same time, one of my favourite episodes so far actually.
