Even on The CW, debuting with a 0.2 adults 18-49 rating is not great. No series premiere in the past three seasons on the network has come in that low, and only two returning shows (“Reign” last season and “Crazy Ex-Girlfriend” two years running) have premiered with ratings as small.
With The CW expanding to a sixth night next season and “Valor” all but finished — the Bear now has it as a certain cancellation, by the way — “Life Sentence” has a chance to return next season.
It’s not a great chance, but the Bear will start the show as a tossup and see how “Life Sentence” performs into the spring. A more definitive verdict should come in a few weeks.
Note: All of The CW’s shows are produced by network owners CBS and Warner Bros., so ownership of series isn’t a factor.

The Renew/Cancel Index is the amount above (or below) a replacement-level rating — i.e., the expected adults 18-49 rating of an emergency fill-in show should a series be canceled. For the 2016-17 season, replacement level is a 0.7 same-day rating in adults 18-49 for the Big 4 networks and a 0.2 for The CW. (Read more here.) The index number is taken by subtracting 0.7 (or 0.2) from a show’s average same-day rating.
Friday scripted shows (denoted with an “F” above) on the Big 4 have average ratings about 30 percent lower than those of other nights, therefore their ratings are multiplied by 1.43 (1/0.7, or 70 percent) before subtracting the replacement-level number. There is little variance for The CW on Friday, so the multiplier is not used.
Shows that have ended their seasons have their R/C Index number frozen at the point of their final episode.
(O) – Owned: All other things equal, shows owned by studios affiliated with their networks have a better shot at renewal than those from outside producers.
