AVClub: Now this is more like it. With the set-up established, this season gets rolling with two distinct episodes that share common themes significant to Person Of Interest’s overarching story. The show treads familiar territory again but much more creatively than the premiere did. These episodes concern the way that the past informs who we are and comes back to haunt us. They also explore the difficulties of discerning goodness versus evil, who to trust and who to suspect. So much of life relies on being able to identify allies and avoid those with ill intent; because of the unpredictable nature of humanity, this is a more difficult code to solve than a series of letters and numbers. The scariest notion of all is that we ourselves are sometimes the hardest code to crack, and the results aren’t necessarily pretty when we get the answers.
