Think of what we have learned since Sagan's masterpiece was aired. We saw little of that with Tyson, just cartoons of evil religious and other anti-science types.
What did we learn from the new Cosmos show? Well, we unintentionally have learned that modern social politics is killing science. Kind of ironic that everything tyson accused Christian religion of doing to stifle science is in fact what liberals are now doing. In many ways religion was the framework upon which science thrived and brought us out of the dark ages.
