Thursday night’s season premiere of “Nikita,” the CW action series starring Hawaii’s Maggie Q, kicked butt with viewers and drew the largest audience for the network in 18 months, according to Live Plus Same Day Nielsen ratings released by the network.

“Nikita” was seen by an estimated 3.6 million people who tuned into the 9-10 p.m. time slot.

It also matched the network’s all-time best ratings in that time slot for women 18 to 34 with a 1.9 rating and a 5 share. The rating is a percentage of all TV households and the share is the percentage of people watching TV at that time who are tuned in to a particular show.

Maggie Q is a graduate of Mililani High School whose big-screen appearances include “Live Free or Die Hard” (2007) “Balls of Fury” (2007) and “Mission: Impossible III” (2006).
