In week two, this new show came down 14% in the demo to a 2.5 rating with 12.43 million. It won its timeslot. While the numbers are relatively good, it’s the lowest rated new scripted series on the network (not counting A Gifted Man because it’s on Fridays).

Episode 01-01: Tuesday, 9/20/11
This crime drama debuted to a 2.9 rating in the 18-49 demographic and 14.09 million viewers. That represents a 16% increase in the demo over last year’s timeslot occupant, The Good Wife (2.5).

There was erosion of 13% as the first episode progressed, meaning those people tuned out before the hour was finished. That’s not a huge number but those people are less likely to return for the second episode.

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.
