Maybe it isn't real 100 percent history. Some liberties were taken, but for the most part is seems to ring true.At times it almost seems like a contemporary crime drama, but the facts are there-the raids on British monastaries that did occur in the late 8th century, a fairly realistic depiction on what Norse life was probably like at this timeline, the spectacular countryside with its majestic forests and rivers, and the depictions of the Vikings themselves. Savage, eager to loot and plunder, but nevertheless bound by a sort of code of honor. Their acts are savage and the chieftan seems more like a medieval Godfather who uses his power for his own personal gain and who is not above killing somebody on the spot if he is displeased with his actions. The storyline is fairly literate and not the usual mindless adventure that too many of these movies present to us, and the characters are convincingly drawn and likely motivated. The music is good and the full size replicas of the ships are very accurate. Even the deliberate pace works to its advantage, we are never rushed and the story develops as it moves along. It is never dull and there is plenty of interest to engage the viewer. However, if you are put off by graphic violence , don't watch it. Those times were fairly brutal. Fine entertainment . Enjoy it.
