I absolutely loved Tom and Gerri, it's such a wonderfully dark and twisted episode, there is so much more going on then you first realise, plenty of twists and turns, this one is fiendishly clever, with a surprise ending in store. The Twelve days of Christine remains my all time favourite, and this one almost seems like a grounding for that wonderful episode. In so many episodes I heap praise on the guest actors, but here it is definitely the combination of Shearsmith and Pemberton that impress, they are both outstanding in this. It takes maybe one or two watches before you fully understand what's going on, I would definitely urge those of you that have it seen it once to watch again.
Brilliant, a sign of future episodes. 9/10
