Just 3.3 million watched the Ed Westwick serial killer drama. In fact, Wicked City premiered to lower numbers than Forever (http://tvline.com/2015/10/28/wicked-city-ratings-worse-than-forever/), its canceled timeslot predecessor.

I didn't watch it live since I DVR'd it but I thought it was really interesting but having it set in 1982 is what piqued my interest in it more.

But judging by its first episode I dont see it entering a 2nd season unless the writing is strong.
