This was an amazing movie, the plot line, the special effects. I actually cried. It's also very creepy to think that it's 2012 so it gives you that "real" feeling.
Violence - Not much blood or anything.. (one character gets his leg messed up in a huge gear). A lot of the main characters that you get to know die. Two young characters watch as their father falls to his death and another character is ground up in some machinery - yuck, not really anny blood or gore though. There's a boxing match..nothing really except punching. A really bad suicide is mentioned on the news.
Sex - One character is a surgeon who does plastic surgery on breasts. He encounters one of his previous patients, and they discuss her surgery several times. Two characters mention making a baby together. Two characters kiss once, and there's an "almost kiss" between two other characters.
Language - Rare use of strong language, although there's at least one "f--k," a few "s--t," and other words like "d-mn,"
"-ss," "h-ll," "godd-mn," and "oh my God." One character gives another a rude finger gesture.
Drinking, smoking, drugs - There is some drinking to relieve the stress that it is the end of the world.
Overall, it's a very sad movie, and there are a lot of deaths. It has a lot of heavy content so not for young or immature or weak-stomached viewers. Amazing film though!
