Some rules may contain plot spoilers if you haven’t seen the movies.
Teen Movies can’t
If the lead male character has a female best friend, but spends the entire movie in love with another woman, he will end up with the best friend. Some examples are: Secret Admirer, Trojan Wars, Some Kind of Wonderful, and Snow Day
A lot of teen movies promote teenage drinking. Some examples are: Sixteen Candles, Weird Science, American Pie, Can’t Hardly Wait, Scream, I Know What You Did Last Summer
Horror Movies
More times than not, a female victim will fall down while she’s trying to get away from the killer. They also look behind them while they are trying to get away from the killer. This leads to the females falling down in the first place. This can be seen in almost every horror movie.
If the horror movie has sequels, the killer always has to die in different ways. They never stick to what worked in the previous movie. Some examples are: A Nightmare On Elm Street, Halloween, and Friday the 13th
The killer can always catch up to the victims no matter how fast the victims are running. The killer is usually walking at a slow pace, but he can catch up to the intended victims. Some examples are: Halloween, Night of the Living Dead, Friday the 13th, I Know What You Did Last Summer, and Prom Night
The killer’s main target is usually the last person tat the killer wants to kill. Some examples are: Scream 1 – 3, Prom Night, Halloween 1 – 5, Halloween H:20, A Nightmare On Elm Street
The main target in a horror movie is too weak to take on the killer in the beginning of the movie. Fast forward to the end of the movie, the target will become strong enough to take on the killer. Some examples are: Jaws, Scream, A Nightmare On Elm Street 1 – 6, Halloween, and The Blob
The main characters become isolated from the rest of the cast. This makes it easier for the killer to target the victims. Scream, I Still Know What You Did Last Summer, The Faculty, Valentine, and Halloween H:20
When someone (other than the main target) has a weapon to use on the killer, they die by this weapon. Some examples are: House of Wax, Scream, Halloween H:20, Dr. Giggles, A Nightmare on Elm Street 3
The killers always take on psychic abilities. They can always find their victims no matter where they are hiding. Some examples are: House of Wax, Valentine, Scream, Dr. Giggles, Halloween 1 – 6, The Blob, The Bad Seed, and Devil’s Pond
The police force is usually small. Some examples are: Scream, The Blob, Dr. Giggles, I Know What You Did Last Summer, Sleepwalkers, Silver Bullet, Watchers, Halloween 1 – 6, Lake Placid, and Jaws
The main targets will always live. No matter how hard the killer tries to get them. Some examples are: Scream 1 – 3, I Know What You Did Last Summer, A Nightmare On Elm Street 1 – 6, Halloween 1 – 5, Valentine, and many more
Jury Duty movies
More times than not, if a movie takes place from the jurors point of view, there will be a holdout. Most of the jurors will agree, but there will be at least one who won’t agree. Some examples are: 12 Angry Men, We the Jury, The Juror, Runaway Jury, Jury Duty, Trial By Jury, and Death Sentence
Pyschos
Most psycho killers tend to keep clippings of their crimes locked up somewhere. The clippings are usually in a box that will be found later in the movie. Some examples are: Pacific Heights, Misery, Single White Female, and Deceived
