It's cultural studies where they look at how the shows interacted with the time period, issues of the time and how these things change over time and how people reacted to science fiction. And one change that did not occur in the television was a straight switch from good science to bad science.Sturgeon also said "90% of everything is crud". What is the point of studying the BAD science fiction?
One interesting thing about SF television is that it has periodic revivals of anthology shows pop up, like the brief Masters of Science Fiction series they recently did in 2007. You don't really see that for any other type of t.v.
