Ragnar is not a good man, or father and the danger of the character always is present in Fimmel's wild eyes but you still understand why his men fought for him and elevated him so highly that his sons could trade of his name.
There are lots of great characters that appear across the run but at the start the show rests on Travis Fimmel's shoulders and he's really good.
The first few episodes don't really convey the scale of the ones that would eventually follow. Rising to become King, his legacy is cemented by the actions of his sons, particularly Bjorn Ironside (Alexander Ludwig) and Ivar The Boneless (Alex Hogh Andersen) who would rule countries and influence politics far from their homelands. Ragnar Lothbrok (Travis Fimmel) is a farmer and raider who becomes a legendary figure amongst the Viking people by establishing consistent navigation techniques and leading successful raids on the various Kingdom's that would become Britain. Whilst I am not sure I'd consider 'Vikings' to be amongst the very top tier of shows I've watched in my lifetime I've certainly enjoyed my time with the Norsemen. With the release of the last half of the 6th season we finished the epic seven-year saga of Ragnar Lothbrok and his sons.
