Horror Movies Have Rules, Don't They?

The Scream franchise suggested some rules about horror movies:

The first movie taught us how to survive a basic horror film . . .

Rule #1: Never have sex
Rule #2: Never drink or do drugs
Rule #3: Never ever say, “I’ll be right back”

the sequel, Scream 2, reminded us that things change in the sequel . . .

--The body count is always higher
--more blood and carnage
--Never assume the killer is dead

and Scream 3 gave us tips on surviving the final chapter of a horror franchise . . .

The killer is superhuman
Anyone, including the main character, can die
The past will come back to haunt you

and Paul Tremblay's new book Horror Movie plays with all these rules-- and this makes sense because he is balancing three timelines so we're going to need three kinds of horror; the first time period is 1993, when some young auteurs decide to film a low-budget, artsy horror movie and things go horribly wrong; then there are moments from the next fifteen years, as the legend of the "cursed film" grows; and finally, a reboot of this cursed film that was never released, though a few scenes were leaked on YouTube-- and the reboot will contain a cameo from the one surviving actor from the original, the Thin Kid . . . and the screenplay of this cursed horror movie is interspersed between scenes from these three time periods and the screenplay is both aware of the rules of horror and circumscribed by them . . . as is the novel-- this is the first Paul Tremblay book I've ever read  and I truly enjoyed it (and now I'm reading The Cabin at the End of the World and that one is even more compelling-- both books highly recommended if you like the horror genre).
