Blame Canada!

The CW’s new midseason effort, the imported sexy soap The L.A. Complex, set a new benchmark Tuesday night: According to network research analysts, The L.A. Complex is the lowest-rated in-season broadcast drama debut on record (tracking back to the start of the current ratings measurement system).

Despite relatively upbeat reviews, Complex opened to only 646,000 viewers and a 0.3 rating in the adult demo. By comparison, Ringer averaged 40 percent higher in the 9 p.m. slot. Yes, L.A. Complex numbers actually made Ringer look good. Complex also shed half its 90210 (1.2 million, 0.6) lead in.

Other ratings highlights last night were more sunny:

— The second week of ABC’s Private Practice (8.4 million, 2.2) on its new night jumped 29 percent and won 10 p.m. — fans must have realized it moved from Thursdays?

— NBC’s The Voice results show (8.7 million, 3.2) was the night’s highest-rated show, down a tick from last week.

— Fox’s Glee (6.9 million, 2.7), featuring the music of Whitney Houston, climbed 13 percent this week and won 8 p.m. New Girl (5.2 million, 2.6), however, was down a bit.
