Episode 01-02: Thursday, 9/29/11
Episode two came down 13% in the demo to a 2.7 rating and 12.51 million. It was fourth in its timeslot. The network was down by 13% year-to-year and this new series is currently ranking in the middle of the pack on CBS. If the ratings keep going down like this, it won’t take much for Person of Interest to be in the bottom tier and be in serious danger.
Season average: 2.9 demo with 12.92 million.

Episode 01-01: Thursday, 9/22/11
This new drama had some positive reviews but didn’t deliver particularly strong ratings. The first episode garnered a 3.1 in the 18-49 demographic and 13.33 million viewers. It was in fourth place for the timeslot. Year-to-year, aging CSI’s last season debut did 9% better in the demo and 10% better in total viewers.

Some commenters on this site indicated that they felt the pacing was very slow and that seems to match up with the quarter hour breakdowns. Person of Interest started with a 3.3 in the demo and finished with a 2.9 rating. While these numbers aren’t bad, they are hardly what CBS was hoping for.

Note: These ratings are collected by the Nielsen company and are the final national numbers. These are different from the fast affiliate numbers which are just estimates of the actual ratings and are reported on by most other outlets. The final nationals are typically released within 24 hours of the programming or, in the case of weekends and holidays, a couple days later.

What do you think? Do you like the new Person of Interest TV series? Do you think it should be cancelled or renewed for a second season?
