Sleepaway Camp features a highly problematic portrayal of gender identity through its twist ending, where the protagonist's assigned sex at birth is revealed as the explanation for their murderous rampage. This narrative choice associates gender non-conformity with mental illness and villainy, using it purely for shock value without dignity or empathy.
