Parents need to know that Mental is a dark comedy that focuses on a dysfunctional home with five daughters, an unstable mother, a father who's completely removed himself from the scene, and a kooky drifter/nanny who tries to fix both the family and herself. Several storylines feature mental illness, and it's not quite clear whether the nanny is completely sane. There's a good deal of profanity (including "f--k," "s--t," and more), and several moments when the main character uses violence or threats to make her point. One scene includes naked teens fooling around on a water slide (breasts and bottom are briefly glimpsed), and there are other scenes with suggestive material. A teen girl marries an older woman.
