Reception On review aggregator Rotten Tomatoes, Long Bright River has an approval rating of 73% based on 22 critics' reviews, with an average rating of 7.3 out of 10. The website's critics consensus reads, "Carried along by Amanda Seyfried's steely turn as a closed-off cop, Long Bright River takes a winding path with some unnecessary detours but ultimately arrives at a compelling destination." Metacritic calculated a weighted average of 66 out of 100 based on 14 reviews, indicating "generally favorable" reviews.

The series is set in Kensington, a Philadelphia neighborhood frequently associated with crime, prostitution and an open-air drug market. In a review for NPR's Fresh Air, John Powers notes that the series "depicts the characters living in an area of Philly whose decline embodies a profound social collapse ... Propelled by its heroine's search for a killer, Long Bright River isn't just a mystery but a heartfelt story about wounded communities, wounded families and the wounded individuals who try to make things better."

Seyfried's performance in the role was met with critical acclaim, receiving a Golden Globe Award nomination for Best Actress in a Limited or Anthology Series or Television Film. She also earned nominations for Best Actress in a Limited Series or TV Movie at the 5th Astra TV Awards and Best Actress in a Miniseries, Limited Series, or Motion Picture Made for Television at the 30th Satellite Awards.
