The Substance: parents' guide
Best for ages 17 and up. Rated R for strong bloody violent content, gore, graphic nudity and language.
A gruesome body-horror satire for adults, not a family watch, about a fading TV fitness star who injects a black-market drug that spawns a younger version of herself. It takes aim at beauty standards and how show business discards older women, but it makes the point through extreme gore, grotesque mutation and repeated full-frontal nudity, much of it filmed in a deliberately leering way to mock the male gaze. Expect more than a dozen f-words and a finale that soaks an audience in blood. The graphic nudity and relentless gore are why we suggest 17 at the earliest.
What's in it
Violence
StrongRelentlessly gory: a back splits open as a second body climbs out, a woman is beaten at length, a head is cut off with blood spurting, wounds are stitched and fester in close-up, and teeth, nails and an ear come away.
Language
StrongMovieguide counts at least 19 obscenities, most of them f-words; other sources also list s-words, bitch, goddamn, piss and damn. A sleazy TV producer delivers much of it, along with crude, demeaning remarks about women's bodies.
Sex and nudity
StrongSeveral scenes of full-frontal female nudity, often in close-up and some deliberately sexualized, plus a man's bare backside. A couple kisses and fondles on a couch with sex implied, and a TV aerobics show is full of suggestive gyrating.
Drinking, drugs and smoking
StrongThe plot hinges on an injectable black-market drug that the heroine keeps using despite the damage, a clear stand-in for addiction. She also downs several martinis and vomits, and cigarettes are smoked.
Scary or intense scenes
StrongSustained body horror with grotesque transformations, a monstrous creature in the finale and gross-out close-ups of raw meat and rotting flesh. In a fit of self-loathing the heroine furiously smears off her own makeup, and loose teeth are pulled out in close-up.
Sensitive topics
- Addiction
- Self-harm
Worth talking about
The film argues that the pressure to stay young and desirable can push people to destroy themselves. Where do teens feel that pressure today, from ads, social media or celebrities, and how can they push back?
