In case you hadn't heard, the entire run of Cosmos is available to watch (with commercials) for free, on demand on hulu.com
If you haven't seen this series before, what are you waiting for? This is THE series that got me interested in things science. The pacing may be different than modern TV, and science has marched on in many of the fields that Sagan touches on, and he touches on a lot in this series. (Think its just astronomy? Think again!).
Go forth and enjoy.
