The original series has spawned a successful franchise with two spin-off shows and a web series. The spin-offs titled ‘Ravenswood’ and ‘Pretty Little Liars: The Perfectionists’ are set in the same continuity as the parent series and even feature appearances from popular characters from ‘Pretty Little Liars.’ Hence, the shows are spin-offs in the truest sense of the word.

However, the fourth installment in the long-running franchise, ‘Pretty Little Liars: Original Sin’ diverts from the formula of the previous spin-offs. Firstly, the series is an original creation and not directly based on Sara Shepard’s book series. Secondly, it is set in the town of Millwood, a new setting not previously introduced in the franchise. Moreover, it features original characters, and the narrative does not tie into the original show. Hence, the series is pretty stand-alone and a loose spin-off of ‘Pretty Little Liars.’

However, the series captures the essence of Shepard’s works and even features a new iteration of the villainous A. The makers have confirmed that ‘Pretty Little Liars: Original Sin’ takes place in the same continuity as the original series. Moreover, the possibility of the cast members from the original show reprising their roles hasn’t been ruled out. If such appearances do materialize, the series could become a true successor to ‘Pretty Little Liars,’ which went off the air in 2017.

Ultimately, ‘Pretty Little Liars: Original Sin’ is neither a sequel nor a prequel to ‘Pretty Little Liars.’ It captures the nostalgia and aesthetic of the original series and Sara Shepard’s book series. The narrative starts with a clean slate but leaves the door open to connect the story with the greater Pretty Little Liars’ universe. Hence, the series is a spin-off with the potential to serve as a sequel.
