Thinestra
The brief
Nathan Hertz turns body horror into dark comedy with this deranged premise that somehow works thanks to the Macedo sisters' commitment to the absurdity. Melissa and Michelle play dual roles as woman and her literal shed-fat monster, and they lean into every grotesque moment with gleeful intensity. The 90-minute runtime keeps things snappy before the concept wears thin, balancing genuine scares with laugh-out-loud gore that feels more playful than punishing. Perfect for fans of *The Substance* or anyone who thought *Jennifer's Body* needed more literal body transformation.
The verdict
If you love gleefully grotesque body horror comedies like *The Substance* and can handle literal shed-fat monsters turning into dark laughs, this is a delightfully deranged 90-minute ride that commits fully to its absurd premise. If you're squeamish about gore or prefer your horror straight without comedy, you'll find this too playfully disgusting to stomach.
