AVClub: Person Of Interest took the return of Shaw and all of the expectations that came with it as a personal challenge and decided to just go ahead and knock this episode out of the park. The subtitle of “6,741” should be “…Well That Escalated Quickly.” The M.V.P. of this episode and life itself is Sarah Shahi. The brief return of Taraji P. Henson’s Agent Carter is one of the best episodes of the series, and “6,741” is a worthy entry to stand by its side. This episode is successful because it’s ambitious but focused. It delves into almost every genre that Person Of Interest has tackled, but never devolves into chaos. The storytelling is breathlessly efficient, moving, suspenseful, and twisty; the character of Shaw and Shahi’s performance anchor the entire enterprise, ensuring that it stays grounded and on-target. If that weren’t enough, this is one of the most well-executed episodes of a particularly well-executed show in regards to details. The direction is artful; the lighting is divine; the score is on point; the flashback montages are terrifying. In summary, this one should automatically go on everyone’s highlight reel.
