The MPAA has a long list of reasons for Red Sparrow's R rating: "strong violence, torture, sexual content, language and some graphic nudity". That last bit being, I think, that you see a guy's wiener. And there's lots of cigarettes.
Dominika (Jennifer Lawrence) is a dancer with the Bolshoi Ballet, but her career is cut short by a gruesome on-stage collision. (An accident! Or is it?) Not only her career, but also getting cut off is her nice apartment and her ailing mom's health care. Fortunately, she has an uncle who's a bigwig in the Служба внешней разведки Российской Федерации. (Or the "SVR", a KGB-successor organization).
Wait, did I say "fortunately"? No, that's wrong. Because she gets sent to Sparrow School, where comely Russian lasses are taught to use their wiles to seduce SVR targets. Pretty soon Dominika is probably wishing she'd gone to work at the borscht cannery instead. She's given the assignment of seducing American spy Nate, trying to uncover the identity of the mole Nate is running inside the SVR. And most of her superiors in the SVR seem to think she should get a bullet in the back of the head sooner or later, preferably sooner. She's got a very narrow path to walk to survive. And that involves, well, see above: lots of sex and violence, perpetrated by and against all involved.
It's way too long. JLaw keeps losing her Russian accent. (Should have watched more Rocky and Bullwinkle cartoons, dollink.) And her character is sympathetic, but not that sympathetic.
This is another DVD Netflix sent me instead of the disk at the top of my queue, Tenet. And hence another reason I'm dropping my Netflix DVD subscription. After I get Tenet.
