The pros and cons of androids. Very little Spock, unfortunately.
Highlights:
the premise
Corby’s performance, for the most part
Andrea (for me, at least)
Kirk vs. Kirk
actual emotional involvement
Lowlights:
insufficient Spock
stupidity of the setup
Spockism: “Frankly, I was rather dismayed by your use of the term “half-breed”, Captain. You must admit it is an unsophisticated expression.”
