CHRIS Watts has said that the Netflix documentary "brings up awful memories" about murdering his pregnant wife and two daughters.
"American Murder: The Family Next Door" premiered on Netflix on Wednesday.
The program discusses the brutal murders of Shannan Watts and her daughters Bella and Celeste.
Watts was convicted for the murder of his pregnant wife and two daughters after their bodies were found at a nearby oil plant.
A source told People magazine that Watts is bothered by the new show.
"He's curious about [the documentary], but he hates even knowing that his texts are out there for the public to read. It brings back awful memories of 2018 for him.
"He can't see it, and he’ll probably never see it," the source said.
Watts pleaded guilty to their murders during a court appearance on November 6, and was sentenced on November 19.
His guilty plea came after a plea deal to avoid the death penalty.
The 33-year-old was arrested on August 21, 2018, on suspicion of murder by police in Denver.
His wife Shanann and the couple's two young daughters were found dead at the oil and gas exploration site where he worked.
Shanann was 15 weeks pregnant with their third child at the time.
On November 6, 2018, Watts sobbed in court as he pleaded guilty to five counts of murder in the first degree, three counts of tampering with a deceased human body, and one count of unlawful termination of a pregnancy.
The request not to seek the death penalty came from Shannan's family.

Watts had previously denied the charges and even made a tearful TV appeal for his family's safe return after they were reported missing in Frederick, Colorado.
Shannan's body was found buried in a shallow grave and the girls had been dumped in oil tanks on the property of Watts' former employer - the Anadarko oil and gas site.
Watts is currently serving life in prison without the possibility of parole.
