The Sinner season 3 recently concluded and delivered an emotional finale. But despite that, the future of the anthology drama series is still uncertain as of yet. It remains to be seen whether USA Network will renew or cancel The Sinner season 4.

At the moment, USA Network hasn't made any official announcements about the renewal status of The Sinner season 4. According to CarterMatt, there is no pressure to bring back the series for more, given that it has an anthology structure.

Perhaps, the renewal of The Sinner season 4 may depend on whether there's a reason to bring it or not, if there's a pitch that would generate a large audience, and whether the ratings are good enough. The biggest challenge here is that the ratings of the current season are, reportedly, far from great.

The latest installment featured Matt Bomer and Bill Pullman, and it only generated an average of 0.2 ratings in the 18-49 demographic, as well as 650,000 live viewers an episode. These numbers were significantly down compared to what the series drew back in season 2.

Although some viewers are checking the show via DVR and streaming services, that may not still be enough. Another concern here is that there is a huge gap between the end of season 2 and the start of season 3. Hence, viewers may need to wait for another year before seeing The Sinner season 4.

Moreover, the third installment also premiered during the winter rather than the spring, which could've factored in the decrease of ratings. For now, the decision about the renewal of The Sinner season 4 is still up on the USA Network.

As for what happened in the season 3 finale, Bustle reported that showrunner Derek Simonds has an idea where Detective Harry Ambrose's (Pullman) story could go in the future. He said he'd like to see him grapple due to what happened to Jamie Burns (Bomer).

It looks like Pullman is also interested in continuing the series and agreed with Simonds' vision for Ambrose in the potential future seasons. The actor said the series is an "incredibly rich experience" for him since it deals with subtle psychological truths, which keeps him awake.

Yet, season 3 finale also ended with Ambrose displaying his own pain and opening up. This may be a fitting ending, where he dedicated himself to investigating the trauma of others. Simonds noted that he'll be very satisfied if ever the show ends there.
