I'm reading some of the complaints and I think I laughed a little at some of these ridiculos people. Every time I see the comment of iTs nOt likE netFliX vIkIngs" I cringe a little. spoiler alert: Netflix is vikings is the most inaccurate, american-washed series and I can't watch it due to the fact it's so stupidly done, dramatic and does not follow lore well at all.
This movie? Follows the viking lore to the T. Vikings were pagan, so of course the movie is going to focus on paganism!! This is exactly how they fought, thought, etc. Everyone complaining about having to see that is stupid, what did you want to see? Them praying in front of a church? Boy, americans are weird.
The bottom line is, I wish the movie had a higher budget so some of the special affects wouldn't be as questionable. But the plot itself is excellent, and I think the movie gives a true insight into viking culture and lore.
