Despite the low rating given this movie, I found it both entertaining and interesting in terms of historical events. Certain scenarios may not be totally accurate or true to our modern eyes and beliefs, but the overall feel and look of the movie is solid. There is tension, some good characters and lots of nice period detail. A few very minor issues can be overlooked, like the way the neck scarves are being used - no one wore them that way until recently, and the inside of the ship (especially the bridge area), seemed to have been pretty warm as no cold steam or breath was seen during their Arctic journey. But this is apparently based on real events and so for me it is one of the better productions, with good writing, acting and not too much action that is unnecessary to tell an important story of how these convoys were vital to the war effort for the allies.
