The legal controversy surrounding ABC's new reality offering "The Glass House" did little to boost its premiere Monday night.
The series premiere -- which sparked a lawsuit from CBS last month over its alleged similarities to that network's "Big Brother" -- drew a 1.6/4, down 33 percent from the equivalent summer premiere of "Extreme Makeover: Weight Loss Edition" last May 30.
Meanwhile, while cantankerous British chef Gordon Ramsay cooked up a narrow ratings win for Fox with "Hell's Kitchen" and "MasterChef," according to preliminary numbers.
Fox took first place in the advertiser-friendly 18-49 demographic with an average 2.4 rating /7 share, and placed third in total viewership with an average 5.5 million.
"Hell's Kitchen" at 8 p.m. posted a 2.5/8 in the demo -- down 11 percent from last Monday's episode -- and 5.6 million total viewers. "MasterChef" the following hour was also down, sliding 15 percent from last Monday for a 2.3/6 and taking 5.5 million total viewers.
NBC took a close second in the demo with a 2.3/7 and first in total viewers with 7.5 million. Though down 15 percent from last week for a series low of 2.8/9, "America's Got Talent" at 8 p.m. was still the top-rated show of the night, and was also the most-watched with 11.2 million total viewers. "American Ninja Warrior" dropped slightly for a 2.0/5, and drew 5.8 million total viewers.
ABC grabbed third place in ratings and second in total viewers with a 2.0/6 and 6 million. "The Bachelorette" at 8 performed flat with last week with a 2.3/7 and drew 7.2 million total viewers. The series premiere of "The Glass House" drew just 4.2 million viewers.
CBS, which ran repeats throughout the night, took fourth in ratings and total viewers with a 1.3/4 and 5.2 million.
