It's wonderful to see an episode that takes risks left and right, particularly when, as in this case, they all pay out wonderfully. So we've got the Enterprise and this alien ship locked in battle. That's certainly cool, but nothing terribly innovative. In addition to the clever game of cat and mouse that fills the bulk of the episode, however, the narrative is enriched beyond the norm on both sides of the line. Aboard the Enterprise, we're treated to an intimate look at both discord among the upper ranks with the vengeful Stiles, and loss on the lower decks when the battle costs the life of a young groom to be. Riskier still is the time we spend aboard the Romulan vessel. Here we have a commander campaigning ruthlessly to destroy our heroes, and coming rather close several times more than we might like. He's not just good at his job; he's Kirk good at his job. But because he carries out his mission reluctantly, because that is the job he is born to perform, we sympathize with him, though we know we may not show him any quarter. The rules of this game make it so that only he or we may survive - our rejoice at victory is coupled with regret that it must also mean their defeat. Superior storytelling.
