Defiance is off to an extremely strong start on Syfy.

The drama, which debuted last night, garnered 2.7 million overall viewers and 1.3 million among adults 18-49 for its two-hour pilot, becoming the channel's most-watched scripted episode in the latter demographic since the 2006 opener of Eureka.

And its most watched premiere in general since Warehouse 13 in 2009.
