On one level this could appear a simple film with a simple plot. Some people may struggle with scenes where there isn't much dialogue, where you have to let what you are seeing tell you how the various characters are feeling and what they might be thinking. Personally I felt this made the film feel very realistic as it didn't try to do the thinking for you. I particularly appreciated way the film creates the balance of tension between what is happening on the ship, and what is happening back 'home' with the negotiating team. You then realise that whilst Mikkel Hartmann is hostage, the CEO of the company Peter Ludvigsen is also a 'hostage' of sorts as he battles with his emotions in order to do the 'right' thing. A very enjoyable movie!
