History has so many lessons, This series is a magic mix of great music, character depiction, the intensity of medieval life, heroism and by far the best historical drama, action, adventure series I have watched. I was so impressed till season 3/4 when Ragnar dies and felt maybe I cannot continue watching. But everyone in the next generation of Ragnar is so well suited, I am enjoying the post-Ragnar show as well. Great Series, Enjoy watching.
