TV Ratings: Transplant Flatlines in Season 2 Premiere, American Idol & The Rookie Rise

The long wait for Transplant Season 2 concluded Sunday night, but it looks like many viewers forgot the show was back ... or they lost interest after such a lengthy hiatus.

Transplant Season 2 Episode 1 managed 1.3 million viewers and a 0.1 rating -- way down from last season's premiere (4 million/0.4 rating), finale (3 million/0.4 rating), and average (3.5 million/0.4 rating).

The series has already been renewed in Canada for a third season, but it's unlikely NBC will pick up the rights to air it if the numbers continue to be this low.

Elsewhere on NBC, The Courtship -- a Bridgerton-esque dating series -- got off to a lowly start, with fewer than a million viewers and a 0.2 rating.

In The Eye of the Storm followed with 2.2 million viewers and a 0.2 rating.

Over on ABC, American Idol is showing impressive resilience, rising to 6.3 million viewers and a 1.0 rating in the demo.

That demo tally puts it well ahead of the other ABC fare, and bodes well for another pickup.

It's amazing that the show was deemed a moderate performer when it launched as a reboot, but it is holding up very well.

The Rookie benefited from the increased lead-in support, spiking to 3.8 million viewers and a 0.5 rating.

Over on CBS, The Equalizer (6.9 million/0.6 rating) and S.W.A.T. (3.9 million/0.5 rating) each gained a tenth, while NCIS: Los Angeles (5.4 million/0.5 rating) was steady as a rock.

Of those shows, The Equalizer and S.W.A.T. are locks for renewal, but NCIS: LA is on the bubble.

FOX's animated comedies The Simpsons (1.5 million/0.4 rating), The Great North (1.1 million/0.3 rating), Bob's Burgers (1.1 million/0.3 rating), and Family Guy (1.3 million/0.4 rating) were all stable with their prior results.
