Parents need to know that the series' adult characters bicker and have trite, insincere miscommunications. They also forgive each other and care tremendously for their kids -- despite the normal ups and downs of a middle class American family, nothing seems to interfere with this strong familial bond. There's no violence (except occasional accidental falls and sibling squabbles), but the language is a bit iffy, as are the sexual innuendos.
Positive messages:The family unit is strong. They may have arguments or miscommunications, but they always come together in the end. Some typical family sitcom gender stereotyping, and the cast isn't at all diverse.
