Cosmos isn't really speculation. Sagan delivers the facts of the universe in a beautiful way, and yes he does add his own thoughts on things not yet proven, but I respect his opinion very much.
And yeah, if you're not into it, you won't like it. Pretty simple. I know none of my friends would sit through an episode, or i don't even think my friends read. Today I found myself reading my astronomy textbook. My test was on Saturday, and i'm still reading the book. Thats the good thing about life. Find something you like and go with it.

I`m reading actually two books right now....
One is an older book by Bill Gates called "The Road Ahead" Quite interesting.
Also "Into Thin Air" John John Krakauer, which is about a real life of a man who climbed Mt.Everest.. read it a couple times and I recommend this.
