In the return of the History Channel’s Vikings, viewers will expect to be reacquainted with all the savagery and remorselessness of writer-creator Hirst’s compelling universe. Pitiably, the second season’s first offering, “Brother’s War”, is a patchwork of the first season’s dramatic elements, and one that’s shot through with lead-footed dialogue. In it, Ragnar (Travis Fimmel) remains where he was last left, the newly appointed leader of his people, despite opposition from his Loki-esque brother, Rollo (Clive Standen). Considering this complex relationship, Rollo’s surrender to Ragnar on the battlefield (and his later release by virtue of some anticipated divine plan) feels unwieldy, the narrative buckling under the need to save an intriguing character from an anticipatable fate. The title of the episode’s a little a bit of a misnomer then; tonight’s focus is upon Ragnar’s ongoing connection to the sea, and all the ties that come with it: personal, spiritual, and fortuitous.
