I have been waiting to see last Friday's ratings and how the premiere of Boston Blue did. Both TV Series Finale and Spotted Ratings don't have anything yet almost a week later. I found out Spoiler TV doesn't even cover ratings anymore, their last updated posts were from August.

Programming Insider still covers Nielsen Ratings this season.

Here's the ratings for last Friday (October 17), featuring the Boston Blue premiere:
