The Post-Gazette reviews movies from a family perspective:

Rating: PG-13.

Suitable for: Mature tweens who can handle sad material and older moviegoers.

What you should know: This is based on the Jodi Picoult book about a girl who goes to court to avoid giving her ailing teenage sister a kidney. The movie shows what can happen to a family when one of three siblings is gravely ill (here it's leukemia) and examines questions about conceiving and engineering a child to try to save another's life. Many people were crying at a preview.

Language: One f-word, a couple of uses of "Jesus Christ," some profanity and mild expletives.

Sexual situations and nudity: A teenage girl and boy kiss or recline on a bed after an amorous interlude.

Violence/scary situations: Cancer patients appear with bald heads and are shown vomiting or suffering nosebleeds and other effects of their disease or treatment. Two characters die, off screen, and another suffers an epileptic seizure. A reference is made to a 12-year-old girl killed by a drunken driver.

Drug or alcohol use: A distraught teen mixes alcohol with some prescription pills. Adults drink beer or wine.
