This extremely brutal and bloody sci-fi thriller is brilliant and very entertaining, but again is too much for even older teenagers. This movie is about a man named Curtis, who has been on an iron train name Snowpiercer for 17 years after rich people have saved them from earth after global warning turns the whole world into below freezing, cold, and completely frozen. On the train, there are different sections, the front, the middle, and the back. The front is for rich people and who are royal to the leaders of the train and the front of the train as well, and the back is for poor, homeless people who don't get clean food or water. The train is non-stop, and has been going ever since 2014, and is still running in 2031. Curtis is completely tired of being treated this way, and his mission is to get to the front of the train to the water supply, and to take over the train. He can't get to the friend without his friend, and Namgoong, who is a specialist to help Curtis open the gates to the front. Violence 4/5: Violence in this adventure is very bloody and very brutal.
