Common Sense Note

Parents need to know that although this fable-like indie dramedy doesn't have too much iffy content when it comes to sex (some kissing and implied intimate moments), drinking, or language ("a--hole" is as strong as it gets), it deals with some fairly heavy subject matter -- such as death and dysfunction. One person's father suffers an infirmity; another has a sick mother in the hospital. The lead character is clearly emotionally stunted and has many fears, but she does overcome them.

Sexual Content

A couple is interrupted mid-intimate moment; their bare shoulders are visible. Another couple is shown clothed in bed, under the covers. Some kisses.


Two kids threaten to chop each other up with an axe, but it ultimately hurts someone else. A girl slams her head against a glass pane, hurting herself.


Words used include "skanky" and "a--hole."

Social Behavior

The movie's central take away is that love doesn't require you to lose parts of yourself, but you'll have to trust in love to learn that truth.


A mention of M&Ms and Cheerios.

Drugs / Tobacco / Alcohol
