That is a shame, maybe you can find it on netflix or hulu but anyway here is a preview of it. It kinda sucks when public broadcast tv is blocked just because you are in another country. PBS offers so many great documentaries on history, sciences, and the arts that should be free to everyone. Same with BBC programing on a similar level.
