In a dream sequence, a man is seen lying with his wife, and the camera pans under the bed covers to where a bearded, haggard looking man is seen reaching out with his arm. A very quick scene that doesn't overstay its welcome.
There's a general sense of threat and tension throughout, especially towards the end.
A fight is quite bloody and disturbing in tone.
The movie has a slow pace and its plot is complex, most likely not to be enjoyed or understood by children.
