Common Sense Note
Parents need to know that this lightweight, sun-kissed musical will likely appeal to the teen girls (and their moms) who make up much of the fan base of the Broadway musical it's based on. Language is quite tame overall ("ass" is about as strong as it gets), but sexual innuendoes do fly -- there are plenty in the ABBA song lyrics alone -- and one of the main characters is a woman who gets pregnant but doesn't know who her baby's father is. There's also a brief, non-sexual glimpse of a man's bare butt and a fair amount of drinking, but it's mostly in the context of everyone having fun on a Greek island, and it's all pretty social in nature.
Sexual
Content
Sexual innuendo in song lyrics and conversations (for example, a hand drill is waved around in a suggestive way to signal sexual intercourse). One character is very open about her cougar-like sensibilities, preying on a younger man -- and vice-versa. Lots of reminiscing about sexual escapades of the past. One scene shows a man's naked backside, though not in a sexual context. A sex toy is seen briefly during a dance sequence. A quick kiss between two men; one key character turns out to be gay.
Violence
Men and women yell at each other about past disagreements and misunderstandings; a mother and daughter argue.
Language
Fairly tame, with a few uses of "ass," "crap," and "frickin'."
Social
Behavior
Allusions to infidelity, abandonment, and sexual indiscretions. A daughter lies to her mother about inviting three men from her past to her wedding. Otherwise, truly earnest and warmhearted..
Consumerism
A few labels: Duke University T-shirt, logos for Greek taxis. And, of course, the entire movie helps promote ABBA songs (and also the Broadway musical the movie is based on).
Drugs / Tobacco /
Alcohol
Lots of alcoholic libations, but they're only consumed in social settings. Some cigar smoking; references to weed.
