影片颇具写实风格和记录感，意在为观众营造出一种身临其境的孤独和恐怖感，从而思考生命的意义，为此还放弃了那种英雄主义的模式，人类在与狼的战斗中，没有占到一丝一毫的便宜，最终只剩下了连姆尼森一个人。片尾以连姆尼森做好准备迎接狼的进攻这一镜头，戛然而止。片中所有的狼那么逼真，一定有人认为它们是剧组训练好的动物演员，其实不然，片中所有的狼都是电脑CG制作的。那些北极狼，个头很大，又臭又凶，吃起人来就异常血腥，一个个人类的血染红雪地，非常挑战观影神经。而人群的反击也同样像野兽一样残暴，比如片中众人

Visitor pattern decouples the data structure from the operations acting on the structure, making the operation set relatively free to evolve. Visitor pattern is suitable for systems with relatively stable data structure and easy change of algorithm. Because visitor mode makes it easy to increase algorithm operation. If system data structure objects are easy to change and new data objects are often added, visitor mode is not suitable. The advantage of visitor mode is that it is easy to add operations, because adding operations means adding new visitors. Visitor mode centralizes the relevant behaviors into one visitor object, and its changes do not affect the system data structure. Its disadvantage is that it is difficult to add new data structures. -From Encyclopedia
