A bit of a mess: Channel 4’s Generation Z reviewed

In the second of this week’s two episodes of Generation Z (Sunday and Monday), a teenage girl called Finn wondered why her friend Kelly was so distracted and tearful. As a well-informed type, Finn applied the principle of Occam’s razor and decided that Kelly must be pregnant. In this case, though, the simplest explanation definitely wasn’t the right one. What was ailing Kelly was that her nan had tried to stab her with a large kitchen knife prior to feasting on her flesh – until a male schoolfriend turned up, shot her nan with a crossbow and hid the body in the woods.

In some British towns, all this might have been something of a one-off. But not in the fictional Danbury, where an army lorry had recently shed its load: a gas that causes old people to develop a sudden zomboid taste for blood.
