Matt Bomer Cameo Doesn't Keep 'Glee' From Season-Low Rating

"Glee" once more graced FOX's 8 PM ET/PT after its six-week hiatus, but even Matt Bomer's talked-about guest spot didn't stop it from putting up disappointing numbers.

The exceptionally talented "White Collar" actor portrayed the older, exceptionally talented actor brother of Darren Criss' Blaine Anderson. Despite a show-stopping performance of Gotye's "Somebody That I Used To Know", the hit musical comedy's competition proved just a bit too stiff. It outperformed the sitcoms aired the past six weeks during the show's typical Tueday slot, but with 6.7 million viewers, the 2.7 adult demographic rating marked a 10-percent slip from its last original in February to a season low.

According to Entertainment Weekly, FOX has noted that the hour's overall 8 PM slot viewership across the board has fallen 9 percent since "Glee" went on hiatus, due to the Daylight Savings Time shift forward an hour.

Still, it's such a FOX institution that there's no way a rating like that exactly endangers the show. It's just not a low rating to which producers and execs want to get accustomed. Though its rating fell off, the show's return still managed to give fellow renewed hits "New Girl" (2.7) and "Raising Home" (1.9) 17-percent rating climbs.

Between First Lady Michelle Obama dropping by "The Biggest Loser" to bump the show up 10 percent to a 2.2, "The Voice" winning the 9 PM hour with a 3.5 rating and "Fashion Star" rounding things out with a 1.8, NBC owned Tuesday night. On CBS, "NCIS" and "NCIS: L.A." slipped respectively to 3.1 and 2.3 ratings, while "Unforgettable" also hit a 1.8 - season-low numbers for all three. ABC's "Last Man Standing" hit a season-low 1.7 and "Cougar Town" kept struggling, notching a 1.5 rating. Worst of all, the "Dancing with the Stars" results show hit a series-low 2.3 mark.
