But Blockers is more self-aware than its premise might suggest, even acknowledging that this scheme isn’t exactly au courant with the sex-positive youth of 2018. So the film gives the parents’ a more measured rationale: Lisa (Mann) and Mitchell (Cena) are afraid of their kids having sex, not because they want to protect the girls’ virtue, but because sex signifies a passage into adulthood and independence. Blockers offers a surprisingly apt framing for a generational clash as old as time—the parents who think of themselves as progressive and cool, versus their mortified children who view them as anything but.
Lisa is a single mother who is intensely close with, and protective of, her daughter Julie (Kathryn Newton of Big Little Lies and Halt and Catch Fire). Though Lisa initially thinks Julie is off to college nearby in Chicago, she learns that Julie’s instead planning to go to UCLA along with her boyfriend, Austin (Graham Phillips). Mitchell is a hulking, cargo short–wearing creature of the suburbs who seems like the polar opposite of his loosely wound kid Kayla (Geraldine Viswanathan). Hunter (Barinholtz) is a divorced screw-up who’s despised by both his fellow parents and his daughter Sam (Gideon Adlon)—but he recognizes the foolishness of the “blocking” crusade, and only tags along with Lisa and Mitchell to try and stop the pair.
Blockers works because of the time it invests in its teenaged characters. Each is a delight, particularly the supremely chilled-out Kayla (who decides to lose her virginity largely on a whim) and the more introverted Sam (who knows she’s gay but hasn’t quite figured out how to tell her friends and family). Despite Blockers’ title, the script (by Brian and Jim Kehoe) is much more invested in the girls’ parallel mission to have sex—a plan hatched in a group text that the parents accidentally see.
The discovery of this pact is one of the film’s many clever nods to the most confusing elements of our connected world. Hunter’s limited, Dan Brown–inspired cryptographic understanding of emoji-speak (“Have you seen Inferno?” he excitedly asks Lisa and Mitchell) is enough to crack the baffling code of the kids’ text chain. But by and large, 2018 is a time that truly confuses these grown-ups, who seemingly can’t comprehend that their kids might feel comfortable with their own bodies or be ready to embark on new levels of emotional intimacy. Haven’t these teens even seen a John Hughes film?, the parents might be wondering. Don’t they know they’re supposed to feel awkward and isolated all the time?
As these parents’ Sisyphean chastity quest continues (almost the entire film is set during and right after the prom), Blockers quickly shifts into life-lesson mode: Lisa must learn to be less clingy, Mitchell has to toughen up and accept his daughter’s ability to make decisions by herself (his wife, played by Sarayu Blue, is the more pragmatic of the family), and Hunter needs to make strides toward maturity. Blockers ends up being a mirror-image coming-of-age film, where the kids have to help the adults make some grand realizations.
