The two hour (actually, two back-to-back one hour episodes) premiere of Vikings is on the History Channel at 10:00. The show tells the tale of the epic and violent world of the Norsemen who raided, traded and explored during medieval times. It follows the exploits of historical figure Ragnar Lothbrok and the sagas of Ragnar’s Viking crew and family as he struggles to become ‘king’ of a large part of modern day Scandinavia and Europe. If you like your history violent, this one’s for you. Most of the critics find something to like in the show, here are the reviews.
