Viewers generally find 'Pretty Little Liars: Original Sin' to be a thrilling addition to the franchise, with a more mature and bloodier tone than the original series. The cast delivers convincing performances, and the series successfully incorporates nostalgic elements from its predecessor. While the series starts strong, some feel it eventually succumbs to typical genre clichés and suffers from a lack of sustained pace and overly stretched plotlines.

👍 Strong start with a mature tone

👎 May become clichéd and slow
