* A character is punched repeatedly and later struck with a hammer (the hitting is offscreen). The same character is threatened with a driller near his eye but doesn't get hit by it.

* A character is stabbed with a knife in his head.

* A female character is shown lying in a pool of blood for a couple of seconds.

* Lot of fight sequences, involving mild or less gore.

Mild, mostly muted

Moderate drug consumption including smoking and drinking, along with injecting a drug is visible.

Metro is a realistic action drama involving realistic scenes of violence. The scene of driller near the eye might be intense for some viewers, although it isn't really violent. Also, the scene of a man in helmet stabbed by a rod might be intense. Parental guidance is recommended.
