And so, on the wiki article for Star Trek II: The Wrath of Khan, I found this jewel of story interpretation: 'The Wrath of Khan follows in a long tradition of films in which the adventurer or explorer must undergo a figurative or literal death in order to start anew. Spock is Kirk's doppelgänger and together they represent a bifurcated hero, with the two characters representing dueling halves of the human condition. Spock represents the supernatural ideal of a completely logical and infallible person, while Kirk represents the impassioned and human reality, prone to error and at odds with himself. Spock's sacrifice at the end of the film allows for Kirk's spiritual rebirth in the tradition of the death-rebirth cycle. After commenting earlier that he feels old and worn out, Kirk states in the final scene that "I feel young."' That this insight can be gained at all from media is evidence enough for me that the creative process is an absolutely essential element of the human condition.
