I preferred "Star Trek" (a little earlier, of course)

In the mid 60s, there were some issues you could only get away with, using scifi allegory. Recently, I have been working through the Blu-Ray set, which has a lot of supplemental material. One of the supplements notes that, when the series started, the standing orders from the networks included NO discussion of racism or 'Nam. Some of the later episodes were pretty heavy handed, but, the earlier ones were a bit more subtle. They worked racism into "Balance of Terror". One of the bridge officers took an instant dislike to Spock, when they discovered he looked like a Romulan. This was at a time when some southern TV stations refused to run "I Spy", because it showed a black man being treated equally with a white man.
