I actually like the one where Carl Sagan goes back to his school in Brooklyn to teach the kids.

The special effects of the universe also still hold up really well today.

I really enjoyed One Voice in the Cosmic fugue. So far that has been my most favorite, but I love every episode so much it is pretty hard to choose. It is because of Dr. Sagan that I have started to become an Astronomer. Just as soon as I finish my last semester at my community college I am going to Cornell University. I really cannot wait.
