Continuity mistake: Despite being one of the few slasher films with a PG13 rating, whenever someone is stabbed, their bodies show no stab wounds when they appear again in the movie. The only character with blood stains where they had been stabbed has no holes in their clothing where the stab would have been, only blood stains.
Continuity mistake: While Donna and Bobby are in her bedroom at home, her toes are seen with no polish on. Donna goes to the bathroom to take some pills and returns. A closeup of her feet back in the bedroom shows her with red polish on her toes.
