Messages aren't especially clear, but you could argue for takeaways related to the value of the family we choose rather than the one we're born into. The movie also embraces unconventional but loving relationships.
Brawl between two people who don't know how to fight.
No nudity, but several scenes of a couple in bed -- one in which they try but fail to have sex (played for comic effect), one in which they succeed, and several snippets as part of a montage. Nonspecific discussion of sex.
Rare use of words including "s--t," "hell," "crap," "bitch" and "goddamn." "Oh my God" and "Jesus" used as exclamations.
Brands such as Zoloft are mentioned, but products aren't overtly promoted or placed.
