Great movie. Beautiful visuals and awesome combat scenes. One worry I had is the movie might try to praise pagan violence, but I think it does show it as "yeah these people were barbaric animals" especially in the raid on the slavic people.
The plot is not anything revolutionary, it's a classic tale of betrayal and revenge, but I don't think that's a negative. The movie knows what it wants to do and does it well.
I'm surprised there are so many 1 star reviews on google... especially considering I KNOW these mfs line up to watch the latest Marvel/Star Wars movie/show off the conveyor belt. What a shame. Don't let it deter you from seeing this awesome film.
