Not the worst way to spend an hour. The vikings themselves look pretty bad ass and the wife of the main protagonist is really hot and strong.
It's based on Ragnar Lodbrok and there's all kinds of talk about Valhalla and Odin and they're pretty much starting to raid England.
Neat.

I'm kind of surprised this show has lasted as long as it has, and according to this source, has been renewed for a 5th season:

At times the show can draw me in, and at others the writing is extremely basic and loses me completely. However, I'm getting to the point where I was with Sons of Anarchy...I've watched it to this point...I'm going to see it through to the end, damn it.
If anyone likes this show, you may like The Last Kingdom on Netflix. I'm 6 episodes in there, and am still enjoying it.
