We've seen this story told many times before but this still seems fresh and the acting is quite good. A little slow to get started but when it does, it's quite suspenseful. It's worth a watch, and the Icelandic settings are a relief from the usual American locales.

Possible Spoilers!I gave this very worthy flick 10 stars just to redress the balance of the negative reviews it has received here.Works on all levels. The dramatic tension is consistent throughout. The father/daughter relationship is very realistic, particularly her lack of self awareness and immaturity wich are very recognisable traits of addicts. Gísli Örn Garðarsson was convincing as Ottar. He wasn't painted as just a two dimensional villain. Just as real villains are not just villains. They love, have families, have a sense of humour, pets and hobbies and are often victims of bigger villains than themselves.I laud Baltasar Kormakur as both a fine director and actor.

Icelandic auteur Baltasar Kormákur (Contraband, 2 Guns, Everest) directs and stars in this psychological thriller about a father who tries to pull his daughter out of her world of drugs and petty crime, only to find that danger can be found in unexpected places. Eiðurinn lacks dramatic depth and good characters to care about also the film drags and it's a slow burn from start to finish, this film could have been great but it failed on so many levels. (0/10)

Just like the other reviewer had already said, this film is uneven. The plot had potential to be gripping, but failed to achieve it. There are some holes to fill in. Some actions of the main character make sense, the others don't. You just don't start messing up with a drug dealer(s), without making sure your family is secure, especially after they had ransacked your house. What is it exactly he was planning to do with her daughter's boyfriend? I could not figure this out. Why did Óttar got into Finnur' car and allowed him to drive to who knows where? We know that Óttar was not stupid. Besides, Óttar is not the main player in the drug business. There were certainly others who ransacked his house and who would certainly go after Finnur to get their money back. That scene where Óttar talks about his troubled childhood has reminded me a scene in "Breaking bad", Episode 3, where Walt cannot decide whether or not to kill Krazy-8. What was the purpose of bringing into this movie Finnur' childhood? Besides, how would Anna know? They want us to believe that Finnar had told it to her? I could continue with plot holes, but see for yourself. The main 3 character's acting was not bad in my opinion. I am giving it 5 for it is a well-made film overall. Filmmakers should have watched BreakingBad a couple of times to get an idea how to deal with drug dealers.
