Snowpiercer (2014)

Snowpiercer is a cross between Elysium and The Raid on a train, and is basically an allegorical reflection of modern society. Everything takes place on a huge train that circles a frozen wasteland earth. Years earlier scientists released a chemical into the atmosphere in an attempt to stop global warming and inadvertently started a new ice-age. Seeing the impending doom of mankind, a genius called Wilford (Ed Harris) designed the huge train, which uses the earths magnetic field for propulsion..

The train has a class system, with the lowest toward the back of the train and highest toward the front. The people in the tail section live in squaller, packed together on cramped, filthy shelves, with the only food available being black blocks of jelly called "protein blocks". Curtis (Chris Evans) is one of peasants from the tail section - sick of the living conditions, constant killings and lack of food, Curtis plans a uprising.

The population of the train is kept under control by periodical sacrifices in honor of the demigod "Wilford". The sacrifices always come from the tail section of course, and the people are often told to be grateful by their rich, well fed oppressors. The revolutionaries are shocked to discover the way that people live towards the front of the train - with a constant supply of meat, fresh fish, vegetables and eggs. They also discover, to their horror, what those "protein bars" are made of.

On there their way through the train, Curtis, and his friends encounter a carriage full of henchmen armed with machetes and axes - this is a brilliant fight scene. With around 100 men cutting each other to ribbons in a tight train carriage with blood spraying on the windows and some nice slow motion edits.

I'm kind of surprised the film has not been criticized the way Elysium was, because it's subtle critique of society is almost identical. Anyway, Snowpiercer is a descent Sci-Fi drama, with great editing throughout, and some solid performances from the main characters.
