Science

is reducing a scientist's entire body of work to what you saw on that show.

That TV show was watered down so that people with little understanding of current scientific understanding could digest it in hour long segments once a week. Also, it was the understanding of what we knew 50 years ago, so we've moved on considerably.

It was slightly dated when it ran, and PBS has repeated it far beyond it's "best by" date, which is why there is so much criticism of Sagan, especially by the young.

It was what it was, opening minds to possibilities when it was fresh and new, both naive and shopworn in current context.
