iZombie Season 4

The CW’s iZombie appeared to explode its original premise but good at the end of its third season. What had mostly been a crime procedural with a supernatural twist — medical examiner Liv Moore (Rose McIver) is secretly a zombie who helps cop Clive Babineaux (Malcolm Goodwin) solve murders by eating the brains of the victims and temporarily assuming aspects of their memory and personality — radically transformed itself by turning a large chunk of the Seattle population into zombies and revealing the truth about the undead to the entire world. This was such a big event that surely iZombie couldn’t remain the show it had been for three years, right?
