Also, if anyone knows of a map that shows where the Vikings are attacking to and from that would be interesting to see (even if the show is not all that accurate).
It is accurate insofar as, at one point, there were vikings and they did fight with swords and axes and sail in ships. And that's about it. You can gain as much historical insight from watching Game of Thrones.
I've been thinking of starting a podcast akin to MST3000 just making fun of each episode.
We don't have a FAQ for this yet, but it is a commonly asked question. The last thread on it was here.
