first few seasons are truly great, but it does downhill from there. All the best characters get very weak endings, and the accuracy that is "the history channel" declines with every episode. Despite that, Ragnar, his wife, and Rollo carried the show as far as they could. Bjorn could have been the next chapter, but he becomes a side character before you know it. The other young actors are just not as intriguing. Really no reason to take history and make it a fantasy unless you explicitly say you are going to do so. Was pitched as a historical drama, but it far from it sadly. History channel, what happened?
