Just been talking about this with a mate, and realised that one of the things I liked about it, was for the most part the characters are believable, at least on the Viking side - you believe that those fellas in charge are up to it.
In Vikings, Ragnor was great, but Bjorn seemed too dumb, Ivor was a completely unrealistic and unbelievable character, and that alcholic one I forget the name of didn’t look like he’d survive a night outdoors, nevermind a battle.
In this, young Ragnor, Cnut, Eric, Sigefride (especially), Kjarten, all seem like normal but scary bastards you’d expect to be leading an army of Danes.
