Erik Menendez is not happy about a Netflix series that he believes contains “ruinous character portrayals” of him and his brother.

The Ryan Murphy-directed series “Monsters: The Lyle And Erik Menendez Story” has already sparked plenty of outrage and disgust among viewers for glorifying the killers and adding an incestuous subplot. Erik had a different problem with the dramatization of the couple who murdered his parents in 1989, and voiced those concerns in a Facebook post on Friday.

“It is sad to know that Netflix has taken several steps back from the painful truths through its dishonest portrayal of the tragedies surrounding our crime,” he said in a note on Lyle Menendez’s Facebook page.

Erik went on to say that the show was a “disheartening slander” and that he did not believe Murphy was “naive” enough to accidentally change the show in this way.

“Isn’t the truth enough?” Erik wrote. “How demoralizing it is to know that one man with power can undo decades of progress in understanding childhood trauma.”

Erik and Lyle spoke at length about the sexual abuse they experienced as children leading up to the murder, and Erik argued that the show downplayed the stories of victims of sexual abuse.

“The prosecution built the story on the belief system that men are not sexually abused and that men experience rape and trauma differently than women,” Erik said.These terrible lies have been refuted and exposed over the past two decades by countless courageous victims who have overcome their personal shame and courageously raised their voices.”

The brothers were sentenced to life in prison for the murder of their parents in 1996 following their second trial. In that trial, only limited evidence of parental abuse was allowed after the jury failed to reach a verdict in the first trial.
