Warnings: contains mild spoilers for Humans episodes one and two.
A delicious air of tension hangs like cobwebs over Humans, the Channel 4 and AMC co-production which began airing earlier this month. It presents a near-future where a new breed of robots - called Synths - are both cheap and commonplace. They clean our schools, look after our elderly and do our cooking and cleaning.
The Synths carry out their menial tasks with serene eyes and an eerie half-smile, yet not everyone is comforted by their presence. Take Laura Hawkins (Katherine Parkinson), for example: a busy mother of two, she returns home from work one day to discover that her husband Joe (Tom Goodman-Hill) has purchased a Synth called Anita (Gemma Chan) to help with the household chores.
