After five seasons, 91 episodes, dozens of “save the show” petitions and as many Subway plugs on the show, NBC’s quirky dramedy Chuck bowed out last night with two back-to-back episodes. Both hit season highs though neither cracked the 1.5 demo rating or 5 million viewer mark. The regular-slot 8 PM episode (1.2/4, 4.1 million total viewers) was up 9% from last week in 18-49 to post the show’s highest numbers this season. They were quickly topped for the Chuck series finale at 9 PM, which climbed to a 1.3/4 and 4.3 million viewers. While Chuck got an appropriate ending, its finale pre-empted rookie Grimm at a very unfortunate moment, just as the dark fairytale drama was starting a ratings momentum by reversing a slide with a big 29% ratings gain last week to a 1.8/5 in 18-49. With a weaker lead-in, NBC’s newsmagazine Dateline (1.1/3) was down 21% from last week.

With CBS’ lineup in repeats for a second consecutive week, ABC (1.6/5, 5.5 million) finished again as No.1 in 18-49, while CBS (1.1/4, 7.5 million) kept the total viewer crown. Univision (1.5/4, 3.6 million) was a major demo factor, finishing a very close No.2 for the night in 18-49. ABC’s Shark Tank (1.6/5) held up well in Week 2, down a tenth from its season premiere and dominating the 8 PM hour in 18-49. It finished a close second for the night in the demo behind its lead-out, Primetime: What Would You Do? (1.7/5), which was up a tenth from its season premiere last week. But 20/20 (1.5/4) was down 17% from last week’s special on the Italian cruise ship disaster. Fox’s Kitchen Nightmares (1.4/4) continues to struggle against unscripted rival Shark Tank, dropping another 13%. Fringe (1.2/3) was up a tenth from the series low it had been stuck at for the last couple of weeks.
