From Wikipedia: Scream offered a self-referential approach to horror by featuring a cast of characters aware of the conventions/clichés of the horror film genre and able to use them to survive. The film focuses on teenager Sidney Prescott as she comes under attack from a mysterious character dubbed Ghostface while dealing with the anniversary of her mother's murder. The film went on to be a financial success and received considerable critical acclaim for its deconstruction of the horror genre. It is credited with revitalizing the horror genre in the mid 90s and inspiring an array of imitators.

I feel like this has to be exceedingly rare.
