Pll the perfectionists hits all the right spots. It references the OG at perfect moments. It also shadows a lot of the plot points from the OG just enough for OG fans to get the reference but doesn't make it obvious enough for new viewers to feel like they're missing something. For new viewers, it feels like watching a cool new show. For fans of the original, it feels like watching a continuation of pll. I was at first worried that it would feel too separate from the original but in a way, it continues storylines from the finale of pll. All in all, you can expect a great show.
