NBC’s attempt to improve its fortunes on Wednesday by replacing underperforming (and already cancelled) newbie Animal Practice with sophomore Whitney is not working, at least not from the get go. In its second season premiere last night, Whitney (1.4/4 in adults 18-49) matched the debut in the Wednesday 8 PM slot of its predecessor Animal Practice. It was down 30% from Whitney‘s debut in the time period last spring and tied as its series low. Guys With Kids (1.3/4), the only Wednesday series to still be awaiting a decision on a back order, was flat with two weeks ago and also tied as a series low. Law & Order: SVU (1.6/4) was down 6% from two weeks ago, and it too tied its series low. After the big ratings jump last week when it followed an original Voice, newly picked up Chicago Fire (1.6/5) retreated 27% for a net gain of .1 vs. its original two weeks ago. But it held onto 100% of its lead-in, something no other 10 PM rookie drama has been able to do this season.

The other new Wednesday 10 PM drama that received a full-season order over the past week was ABC’s Nashville (1.8/5), which reversed its ratings downtrend last week with a .2 uptick. But the rise was short-lived as the soap dropped .2 last night to return to the series low level of two weeks ago. The entire ABC Wednesday lineup was in negative territory last night. The Middle (2.5/8) was down 7%; The Neighbors (1.9/5) down 10% to tie its series low; Modern Family (4.6/12) down 4% and Suburgatory (2.4/6), which continues its pendulum swings, down 17% from last week’s season high to tie its season low.

Fox won the night in 18-49 with The X Factor (2.9/8), which finally showed some tangible growth as it heads toward the final stage of the competition. Vs. last Wednesday, when X Factor faced NBC’s The Voice, The Top 12 performance show was up 12% in 18-49 and 16% in Total Viewers (8.1 million).

CBS’ Survivor: Philippines (2.6/7) was down 7% from last week, while Criminal Minds (3.0/8) was flat. CSI (2.4/7) was the only Big 4 show besides X Factor in positive territory last night, up 4% to top the 10 PM hour. CBS won the night in total viewers.

The CW’s Arrow (3.8 million, 1.2/3 in 18-49, 0.9/3 in 18-34) slipped a tenth each in 18-49 and 18-34 from last week while climbing in total viewers. Supernatural (2.3 million, 10/3 in 18-49 and 18-34) was even in total viewers and 18-34 and up a tenth from 18-49, matching season highs in the demos.
