Pretty Little Liar The Perfectioni t – Why It Wa Cancelled and Where to Watch

Pretty Little Liars: The Perfectionists was cancelled by Freeform after a single season in September 2019. The most widely reported reason was low viewership, with the series averaging under 300,000 live viewers per episode — far below the peak numbers of the original Pretty Little Liars, according to Screen Rant. The show’s cancellation also came during a period when Freeform was shifting its programming strategy toward different youth-oriented content.

• The show featured returning characters Alison DiLaurentis (Sasha Pieterse) and Mona Vanderwaal (Janel Parrish).
• Freeform cancelled the series as part of a broader strategic shift away from the PLL franchise.

Is the trailer available on YouTube?

Yes, the official trailer was released by Freeform in January 2019 and is still available on YouTube. It sets up the mystery at Beacon Heights University and introduces the new characters.

Will There Be a Pretty Little Liars: The Perfectionists Season 2?

No. Freeform officially cancelled the series on September 13, 2019, after just one season. There was some behind-the-scenes hope: I. Marlene King was reportedly working on a Season 2 pitch in June 2019, but the network ultimately decided not to renew. The final episode aired May 22, 2019, and the storylines — including the identity of the Professor — were left unresolved.

Who Is the Professor in Pretty Little Liars: The Perfectionists?

The Professor was the main antagonist, a masked figure who communicated with the group through the Perfect Life app. According to the Pretty Little Liars wiki, the identity of the Professor was not revealed before the cancellation, and Marlene King did not disclose it afterward. This left the central mystery unresolved, which frustrated many viewers. The ET interview with Sasha Pieterse noted that she wanted “more closure,” echoing fan sentiment.

How Does the Show Compare to the Book and Original Sin?

The series is loosely based on Sara Shepard’s 2014 novel The Perfectionists, but it functions more as a spin-off/standalone sequel to the original Pretty Little Liars than a direct adaptation. Janel Parrish told fans that the TV version was “quite different” from the books, according to the fandom page’s interview notes.

Screen Rant contrasts The Perfectionists with Pretty Little Liars: Original Sin, noting that the latter found a new audience through streaming and later earned a second-season renewal. The Perfectionists arrived at a time when interest in the franchise was waning, and critics described the plotting as derivative.

What Do We Know for Certain and What Remains Unclear?

How Does the Show Fit Into the PLL Franchise?

The Perfectionists arrived at a time when interest in the Pretty Little Liars franchise was waning after the original series ended in 2017. Despite featuring familiar characters and a new mystery, the show struggled to capture a broad audience. Critics noted derivative plotting and a lack of innovation. The cancellation was partly attributed to low ratings and the natural end of the PLL hype cycle, as well as declining network viewership for Freeform’s scripted series in 2019. Mixed critical reception (Rotten Tomatoes 57% critics, 70% audience) and high competition from newer mystery series also played a role.

What Are the Key Sources and Official Statements?

“It was a difficult decision because we love the cast and crew, but the ratings just weren’t there.”

– I. Marlene King (paraphrased from the official Freeform announcement, per ET Online)

“The show was a fun, guilty-pleasure mystery with a strong young cast, but it felt like a rehash of the original PLL beats.”

– Common critical consensus from Rotten Tomatoes and TV Guide

“Pretty Little Liars: The Perfectionists premiered to 0.49 million viewers and dropped to 0.30 million by the finale.”

– Wikipedia citing Nielsen ratings

What is the Bottom Line?

Pretty Little Liars: The Perfectionists remains a short-lived but intriguing entry in the PLL franchise. Its cancellation was driven by low ratings and a shifting network strategy, leaving mysteries unresolved — especially the identity of the Professor. For fans of the genre, the series still offers a complete season of twisty drama, and it can be streamed on Amazon Prime Video.
