While all of the cast are very watchable in Am I Being Unreasonable? they might as well rename this series The Lenny Rush Show. Twentysomething newcomer Rush, as Nic's son Ollie, pretty much runs away with every scene he is in and he does it again this week when he talks to his mum about the loss of their cat and ends up earning himself some chicken nuggets as compensation.

Elsewhere things continue to take a considerably darker turn. Is Nic (Daisy May Cooper) having a meltdown? a breakdown? Suffering from some kind of PTSD after the death of her lover? When she sees Jen (Selin Hizli) in the street wearing her coat (shades of a sheepskin Don't Look Now as she keeps appearing and disappearing around corners) what is she imagining and what's real?

This blurring of reality and Nic's overactive imagination continues throughout most of the third episode, giving the whole thing a feel at times of Midsomer Murders or Morse as if directed by David Lynch. Am I being Unreasonable? is certainly funny enough to be called a comedy at times (anyone for a story about half man, half prawn in Take A Break?) but it also has more jump scares than a lot of horror films.

The whole series is already available in iPlayer but I've been rationing myself to one a week while desperately trying to avoid any spoilers on Twitter and other social media. But it's a fairly safe bet that things are going to get more dramatic as secrets and lies start to spill out in the coming episodes. With its graveyard ghost story subplot Part three feels very much like a taste of things to come...
