Monday’s TV ratings are in.  Here’s a brief look at the highlights:

• ABC’s Castle was up quite a bit from last week, scoring a 2.2 rating and 10.56 million viewers versus last week’s 1.9.
• Gossip Girl’s final season got off to a rough start as the season premiere garnered a 0.4 rating and 0.77 million viewers, down from last year’s premiere rating of 0.7.
• Fox’s The Mob Doctor was down yet again, scoring a 0.9 rating in the 18-49 demo and 3.46 million viewers, dropping from last week’s 1.0 rating.  Could this be the week that we finally get our first cancellation?
• Hot off a full season pick-up, Revolution garnered a 3.1 rating, dropping from last week’s 3.2.

Hit the jump for the full ratings report for Monday, October 9th, including How I Met Your Mother, Bones, 2 Broke Girls, Partners, and more.

NBC 

• Though last week the series scored a full season order from NBC, the new genre series Revolution slipped slightly.  The episode was down a tenth with a 3.1 rating versus last week’s 3.2, though the total audience of 8.2 million viewers was steady.  The episode saw the death of a “major” character, but promised some much-welcomed character development in the coming episodes.

ABC 

• ABC’s Castle was up three whole tenths from last week’s episode, scoring a 2.2 rating in the demo and 10.56 million viewers.

CBS

• How I Met Your Mother kicked off CBS’ comedy night, scoring a 3.2 rating and 8.1 million viewers for a disappointingly subpar episode.  That’s down from last week’s 3.3 rating.
• The new series Partners was up a tad, garnering a 2.2 rating and 6.35 million viewers.  That’s up a tenth from last week’s 2.1 rating, but still fairly low for a CBS comedy.
• 2 Broke Girls was again the top-rated scripted series of the night, landing a 3.7 rating in the demo and 10.12 million viewers.  That’s up from last week’s impressive 3.5 rating.
• Mike & Molly was also up, garnering a 3.1 rating and 9.42 million viewers against last week’s 2.9 rating.
• Despite an incredibly low season premiere, Hawaii Five-0 continues its slow climb.  This week’s episode scored a 2.2 rating and 9 million viewers, up from last week’s 2.0 rating.

FOX

• This week’s Bones was down slightly from last week’s episode, scoring a 2.0 rating and 7.1 million viewers against last week’s 2.1 rating.
• New series The Mob Doctor isn’t exactly finding an audience, as the show dipped again for a 0.9 demo rating and 3.46 million viewers.  That’s down from last week’s already-low 1.0 rating.

The CW

• The season premiere of 90210 scored a 0.5 rating and 1 million viewers, down from last season’s premiere of 0.9 but stead with the season finale rating.
• The final season of Gossip Girl got off to a very weak start with a 0.4 demo rating and a paltry 770,000 total viewers.  That’s quite a drop from last season’s 0.7 premiere rating.
