'Glee' Hits New Ratings Low; Is Disco to Blame?

The cast of "Glee" might have been singing "Stayin' Alive" on Tuesday's episode, but the ratings are slowly dying.

Tuesday's "Saturday Night Glee-ver" episode was the lowest-rated episode of the current season, with 6.2 million total viewers. Even worse, the episode managed only a 2.4 rating in the 18-49 demo, the lowest for the entire series.

"Glee" isn't totally alone in this ratings slide, as a number of shows have seen a recent dip in ratings, even some established ones. "The Voice" hit a season low this week as well, and in general spring numbers tend to dip.

But "Glee" is on a clear downward trend. Was this a warning shot from fans? Is the disco theme, and the fact that the episode only included songs from the "Saturday Night Fever" soundtrack, to blame? Are fans only interested in the music at this point, all but giving up on the often-forced storylines?

We'll have to see what happens for the rest of the season, but no matter the outcome, "Glee" has already been renewed for a fourth season. Ryan Murphy has promised a revolutionary way to continue the show despite the graduating seniors, so maybe that will renew interest in the show.

I can say one thing with certainty: continuing guest appearances from NeNe Leakes aren't going to help matters much.
