Actually better than the book

Rating: 9/10 (20 November 2019)

This movie is based on the Chrichton book Eaters of the Dead. He wrote this book on kind of a bet to see if the legend of Beowulf could have arisen from actual events. While the book is good, this movie is the rare instance where it surpasses the source material.
This is the story of a traveling Arab, who comes to be known as Ibn and played by Antonio Banderas. He encounters a group of Vikings and is invited to join them for the evening. The next morning an envoy shows up with a tale of a villages under attack by a group that is invading villages and killing all. The envoy was sent to find help and the medicine woman is consulted. She sees in her bones that the tribe should send twelve warriors, plus one that is an outsider. The 13th warrior status is claimed by Ibn, albeit unwillingly.
After reaching the area that is under attack, the Vikings encounter the fire worm and discover that it is comprised of viscous men that slaughter villages for food, as in they eat their victims. The thirteen decide to seek out this group and kill them in their lair.
This is a very good movie. One could easily see this expanding into the legend that is Beowulf. As I stated previously, it far supersedes the source material and takes you on on heck of a ride.
