Best son was definitely Bjorn, but my personal favourite was Ivar. Love the guys bloodthrist, laugh and manic power so much. Just wish they'd done something more with him rather than having him go crazy and get kicked out the city. I wanted to see him use his vengeance for crazy world domination type shit. I wanted to see him behead every Christian(not cuz I hate them becuz vikings didn't like them lol), behead every citizen of France, and then do some more mad shit. Like that would have goated the show for me. Vikings could have been the TV show version of DragonBallZ but noooo they tried to make it something which didn't need to be made.
