Sex/Nudity: A couple is seen having an affair for about a minute. (They are clothed). A woman is about to get raped by three men and one of the guys says "You gotta pay on your knees baby". Then they are stopped when a guy points out they are being recorded on a camera. A woman is partially naked and covering the top portion of her body with her hands. A couple is seen kissing in some scenes. Violence/Scariness: Lots of over-the-top gruesome violence. A guy rides a train and he slips and falls on blood. He enters another door of the train and we hear the guy screaming. We don't see this action, but we hear crunching noises. In the next scene a guy is hit with a hammer so hard both his eyeballs pop out on-screen. You can see the gashes of blood. The subway butcher is going for the girl now. The girl slips on the man's eyeball and crawls on the bus with blood on her body. A man tries to stop him, but the subway butcher smashes his face in with his hammer (lots of blood). Then the subway butcher decapitates the girl's head with a hammer and we see her head afterward. We see a black man entering the train. Both the subway butcher and man are fighting. The subway butcher hacks him to death and we see the blood. Another man enters the train and all we hear is screaming. Afterwards we can see the man dead on the floor. The subway butcher is shown taking his eyeballs out, toenails out, and his teeth out. A creature rips a human heart out of a lady's body. We see the heart beating. A creature rips out a man's tongue and he is later seen eating his tongue and we see lots of blood in this scene. More gruesome kills should be noted. Profanity: Around 12 f words and it's derivatives. Some anatomical terms, scatological terms, some uses of the word "b****". Name-calling and mild obscenities are heard. Substance use: Characters are seen drinking at a place. One character appears to be drunk from alcohol. Consumerism: A lady is seen listening to her iPod. Message: Bad. A subway butcher that hacks, bludgeons, and decapitates people. Age recommendation: 16+. There are lots of gruesome violence and over-the-top gore in the kills. Some scenes push the R rating. Brief sexual content. A moderate amount of profanity.

Loved it. Very great horror flick. Although, i have to admit, this is probably one of the goriest movies i have ever scene in my life, period. Extreme Blood and gore splattering everywhere in slow motion, as well as tons of other extremely violent scenes. Also has some brief nudity (along with VERY grisly images), a non-graphic sex scene, some language, and bad role models. Guy finds out that killer was killing people on the train to feed these freak monster things (yeah i know that sounds unproffesional :). Altogether, though, this is a very good horror movie with a great story, great acting, and buckets of blood and gore.
