Light.

A guy is shown in a bath tub but nothing explicit is shown.

We see a people in bed a few times but nothing explicit is revealed.

Heavy

Lots of yelling, screaming, smashing things, domestic violence (a tackles his son and the two fight until security comes / a wife kicks her husband a beaut until security drags their feet into the room).

No blood or gore, although a spagetti meal gets splattered across walls and stays there for awhile.

Could be worse for an HBO film:

18 F-words (some with mother), a bunches of $hits (many used explicit), Hells, Damns, @$$es, SOBs, and religious profanity.

Minor

Some talk about alcohol, drinking, and drugs.

Extreme:

This whole film is really intense from start to finish. There is a lot of threatening, yelling, screaming, domestic violence which is disturbing.

At one point a guy tries to kill himself by slitting his wrists but sort of goes into shock before he can do it.

The little girl's crying might add more tension and disturb viewers too.
