somewhere during christmas week where it winter over here and i sat and decide to see this movie only to realise that it be a good choice . it about some oil drill corporation unit send to some part of iceland to drill oil . it concentrate on a white box like structure throughout . when one of the crew member hallucinate presumably due to the release of sour gas and dy in the cold the others realise that there something wrong with a lot of weird thing happening with no explanation . this movie give out an important message which be not clearly show in fact it be hidden and leave for you to figure out . the last winter be about how nature take revenge on man for misuse it and take it for grant . this movie test your think level and how about you perceive thing . if you do not understand it you wont find what message this movie be reveal to u and perhaps foolish while but if you see it in a different way and think accordingly ( i mean just think a little bit more ) you will find it a masterpiece . this be one of the best natural horror film . truly and very gripping and engage . this one a must watch . simply exceptional and outstanding . a new revolution create in hollywood cinema .
