A key takeaway is to develop a strong sense of self esteem so you don't compromise in your relationships. Although Ana starts the movie insecure and upset, she ends it knowing what she does and doesn't want out of her romantic relationship with Christian.
Although their activities are consensual, Christian spanks and hits Ana, usually too lightly to be truly painful but still hard enough to leave a mark. In one scene, Christian hits Ana (with her consent) six times so hard that she cries and leaves, horrified and upset.
Like the book, the movie includes several explicit sex scenes with nearly full-frontal nudity (always breasts and buttocks, and occasionally shots of pubic hair, too). Most of the sex scenes (all of which show Christian opening a condom) involve the use of Christian's ties, eye masks, and other sex toys/bondage aides like whips, chains, handcuffs, ropes, and feathers. Christian and Anastasia walk in on her roommate having sex on a couch; she's wearing a negligee, and her partner's jeans are pushed down under his butt.
Many uses of "f--k," both in the sexual sense and as a declaration; also "s--t," "a--hole," and more.
Featured brands (some very prominently) include Audi, Mercedes, LG, Apple iPhone, MacBook Pro, Volvo, and the Heathman Hotel.
Lots of wine drinking throughout the movie (and incorporated into one sex scene). Ana gets drunk (having shots) at a club and "drunk dials" Christian.
