The Fear

As others have said, Peter Mullan was brilliant.

I enjoyed this series, although 4 episodes was plenty. I was rapidly tiring of Richie's hallucinations (which became repetitive).

I'm no medical expert, by my understanding of Alzheimer's is that it is a fairly gradual decline. Richie seemingly went from having a mild cognitive impairment, to being almost fully incapacitated in a matter of days?
