There is not much to say... I had the privilege of viewing this wonderful documentary and I firmly believe that every person should see it.
It has a lot of facts to share and even if you are not familiar with Sweden's early history (I didn't know absolutely anything about it) that shouldn't be a problem, you'll find out everything you need to know. It's very well narrated, filmed and edited, and Jan Guillou, the series presenter, is really funny and likable.
Bottom line - "Arns Rike" is a very entertaining TV series and you should by all means watch it if you get the chance. For me it got more addictive than all the "Lost"-s and "Desperate housewives" in the world.
