I will be addressing my experience as a regular spectator and from what I’ve learned in my academic institution about film.
I could easily attest that this is hands down a great movie as far as movies go. Set design and costume design was excellent. I’m not sure where people are coming from, critiquing that the characters were not dirty enough - not all Vikings/Norse, especially those around hierarchy, would actually be dirty. Usually, the slaves would be. The love interest, as a slave, was undoubtedly clean, but the context is that she was placed with people that the Uncle deemed of higher value - and worthy to not be treated the same as the rest of the slaves.
I would agree that the pace tailors to modern tv series. And even at the end of the film, before coming to reviews, I had commented that I was surprised it approached the film as a sequence of scenes, similar to episodes of a tv show, since that concept was something more common of films pre-21st century.
My knowledge of its script as independent to a movie alone, was that it was fine. Acting felt good. Soundtrack/sound design reminded me much of the avatar film, and similar war themed movies/shows. I think it was excellent. Visual effects was not something I found interesting at all, as it seemed pretty simple and not “new”. It’s a natural interest to be drawn to getting a new element, and there was not really anything new about this film at all. I do think they went with basic approaches of color significance and black/white significance.
Now, as a spectator, it was interesting enough to me. This is more subjective usually. I like historical renditions and it was hard for me to not pay attention. My eyes were glued to the screen the whole time - aside from squeamish moments. Historical films and historically fictional films are not as popular as superhero/alternative universe movies right now - which I also do enjoy. I’d say it’s not the best movie to watch if you are not interested in time pieces, mythology, historical fiction. To each their own (:
