The best homage were the “letters home” retold through text messages and Facebook status updates. The details added even more laughs with touches like “very old student.” In addition, the use of still images further added to the enjoyment of the episode. Although a risky move, since it was used in about half of the episode, Community nailed it so that it was a strength.
Another story the episode touched on was the changing friendship between Troy and Abed. It touched on how they were both growing up and their adult friendship. It was perfectly capped with Troy and Abed fighting for hours after the war had ended. a touching story that was a nicely included into the overall story arc.
Overall, this was by far the best episode of the season. With it’s zany plot but perfect execution, this episode goes into the vault as a classic episode.
