The parents' guide to what's in this movie.

Positive Messages

Amid all of the action is the message that having compassion can prevent you from hurting others and lead you toward a more courageous path. Also, it takes courage to protect others, even if it means putting yourself at risk. And protecting what's important can take teamwork with like-minded people. 

Positive Role Models & Representations

Sam has done lots of killing as an assassin for The Firm, but she turns a new leaf when she protects a girl who's in danger from other lethal forces. Sam puts her life at risk and brings her family of assassin aunts back together. Their teamwork helps them battle opposing killers. The film’s female focus is notable, with older women (including older women of color) prominently represented in a genre they're often sidelined in.


Lots of killing, including via exaggerated gun violence, decapitation, stabbings, grenade/car explosions, and hand-to-hand combat. Violence also includes breaking bones and dislocated body parts, a person being tased, gunshots, and a knife cut to the cheek. A moment of body horror includes Sam stitching up a wound on her arm. 


Swear words including "hell," "f--k," "f---ing," "s--t," "f---ed," "smartass," bitch," "goddammit," "bastards," "a--hole." Exclamatory use of words like "Christ" and "for God's sake." Words that could be considered ableist, such as "morons," "idiots," "dum-dums," "duh."

Drinking, Drugs & Smoking

Scenes with characters inhaling laughing gas. 

What parents need to know

Parents need to know that Gunpowder Milkshake is an action/adventure film about Sam (Karen Gillan), an assassin who's protecting a girl from another criminal group. While there are themes of teamwork, courage, and compassion, the movie also uses murder and violence in a detached way to create an "exciting" atmosphere, which may disturb some viewers (or glamorize the mayhem). Expect many extended scenes of exaggerated, brutal violence, including gun use, decapitation, stabbings, grenade/car explosions, serious injuries/wounds, and hand-to-hand combat. Swearing is also an issue; language includes "f--k," "s--t," and more.

What's the story?

GUNPOWDER MILKSHAKE centers on Sam (Karen Gillan), an assassin employed by The Firm, which is run by Nathan (Paul Giamatti). But once a job goes south and a girl named Emily (Chloe Coleman) needs protecting, Sam must reunite with her mother, Scarlet (Lena Headey), and aunts Madeleine (Carla Gugino), Florence (Michelle Yeoh), and Anna May (Angela Bassett) to keep Emily safe. 

Is it any good?

This is a stylish but staid addition to the growing subgenre of action films featuring elaborate, cartoonish criminal underworlds. A crude assumption about Gunpowder Milkshake might be that it simply wants to be the "girl" version of John Wick. And the film does seem to base a lot of its comic book-style worldbuilding on the rules established in the Wick films, such as creating a crime community with tons of eye candy, like a 1950s-style diner; a retro, slick hospital that exists outside the bounds of mainstream healthcare; and a library where guns are available for checkout. How do these structures exist without being raided by the police? Gunpowder Milkshake doesn't answer that question. (Neither does John Wick, for that matter.) But while the John Wick franchise does try to explain some of how its world works, Gunpowder Milkshake isn't interested in having those conversations. Instead, it relies on viewers' prior familiarity with John Wick to fill in the gaps of how an implausible world of assassins can exist. That works against the film, since it prevents it from becoming its own entity. 

Despite its star-studded cast -- including heavyweights like Bassett, Yeoh, Gugino, Headey and Giamatti -- the film's focus is more on style than substance. Circling back to the John Wick comparison, that franchise is also full of glitz and glamour amid the killing sprees, but the films boast more threads of pathos than Gunpowder Milkshake. Case in point -- Emily, the girl that Sam is protecting, doesn't mourn her father's death long enough for the audience to internalize her pain and loss. Instead, she either doesn't have enough time to mourn due to the action, or her emotional state wasn't deemed important enough in the script. And her later rationalization about the circumstances leading to her father's death also feels too convenient for the plot. That said, Coleman does a good job at making such lines sound convincing. Meanwhile, Yeoh, Gugino, and Bassett turn in performances that range from passable (Yeoh, Gugino) to clunky (Bassett, alas). Perhaps it's a case of the actors not having enough characterization to latch onto, because we know they can act. As Sam, Gillan isn't charismatic enough to find the fun in her character. Her wooden performance makes it hard to stay interested in Sam's journey from villain to anti-hero. ULlimately, the most convincing actor in the film is Giamatti, who always seems able to turn in compelling performances in even the wackiest of films. With fewer scenes than any of the major characters, his character, Nathan, is the only one who truly grounds viewers in this zany world of libraries full of guns, assassin diners, and mysterious criminal firms. Overall, Gunpowder Milkshake seems more interested in being flashy than in entertaining its audience.
