Regardless of your age, regardless of what you think of war, regardless of what you were hoping they were going to do with Reid's storyline - you must admit that this episode was truly brilliant. On one level, as a typical, profile-and-catch-the-killer episode, it was great - tightly written, well acted, using what the BAU knows about criminals to determine how to catch this one. On another level, advancing the "something is wrong with Reid" storyline, it was excellent. Reid is acting strangely - harsh, impatient, so self-confident that he is appearing cocky, paranoid and defensive. And the team is reacting. Some, obviously, know more than others.
But on a deeper level, this episode dealt with a fallen hero - someone who was damaged by war. And it was topped off with the beautiful reactions of the team when they could not save him. From Gideon to Garcia, the emotions were palpable, real and a fitting end to the story. Television, at its most noble, helps us to be better people. Granted, that goal is very seldom reached, but if one episode could help us see the humanity of a criminal, or the great impact of war on each of us, this was it. Nice job, CM.
