UPDATED: AMC’s The Killing opened its second season with 1.8 million viewers tuning in for its two-hour premiere, 661,000 of them in the adults 18-49 demographic. That was down 33% and 26%, respectively, from the mystery series’ debut last April. The second season premiere was also down 22% from The Killing‘s first season finale. Was it a lingering backlash from the first season ending with no resolution? For the night, The Killing drew a total of 2.5 million viewers for the 8 PM and 11 PM airings. Last year’s impressive cume, 4.7 million, included 2 encores, at 11 PM and 1 AM. At 10 PM, Mad Men (2.9 million total viewers, 1.3 million adults 18-49) was down 17% in viewers from last week’s two-hour fifth season premiere, 19% in 18-49.

Meanwhile, the second season finale of Showtime’s Shameless drew 1.45 million viewers, up 26% from the Season 1 finale. Through 8 weeks of total data, Shameless‘ season two is running 29% above last season. The freshman season finale of House of Lies posted 775,000 viewers, down from the 1.03 million for the series premiere but up from the dark comedy’s most recent airings. Californication ended its fifth season with 768,000 viewers, up 40% from the Season 4 closer. No numbers yet for the second season premiere of HBO’s Game Of Throne last night.
