The premiere of “Scare Tactics,” the Shannen Doherty-hosted series that plays ghoulish pranks on unsuspecting people, chalked up solid Nielsens for the Sci Fi Channel on Friday. But the second week of the network’s new “Tremors: The Series” fell off considerably the same night after a stellar debut.
First the good news: “Scare Tactics” brought in 2.16 million total viewers for its two back-to-back original half-hours April 4 at 10 p.m., numbers 50% higher than Sci Fi’s primetime average. Program also funneled more people 18 to 49 — 1.37 million — to the network than any other original series premiere in Sci Fi’s history.
On the other hand, “Tremors” harvested 2.43 million total viewers over two hours during its two-episode premiere week, but the series managed to deliver only 1.6 million a week later from 9-10 p.m.
Dropoff may cause Sci Fi to reschedule the Wednesday primetime repeat of the “Tremors” episode, which now comes just two days before the new episode airs.
