Content:  The review aggregator website Rotten Tomatoes reported a 91% approval rating, with an average rating of 8.10/10 based on 11 reviews. The consensus reads: "Brutal battles and epic quests help Vikings' fifth season remain an engaging, exciting journey." IGN awarded episode 10, "Moments of Vision", with a rating of 9 out of 10. Entertainent Weekly gave the episode an "A". The second half of the season drew some criticism. Writing in Forbes, Erik Kain said: "the show continues to falter, an unfortunate mix of melodrama, one-note characters and absurd fantasy parading as historical fiction" and that the show "has simply lost its way". In "A Simple Story", Aethelred is portrayed rejecting the throne in favour of his younger brother Alfred. In history, after the death of Aethelwulf, three of Alfred's elder brothers ruled, for two, five and six years respectively, all dying before Alfred took the throne in 871. Writing in Forbes, Erik Kain described the storyline as "just a huge unforced error".
