SLASHER FILM RULES - Friday the 13th: The Final Chapter (1984)

Films have formulas and rules, but how well do films follow those formulas?  Are the slasher film rules true?

Friday the 13th: The Final Chapter (1984) is as the name suggests the final ever film in the Friday the 13th franchise.  Unless the title is lying and they make more.  Whatever happens this is the fourth film in the series.  Just assumed I've asked the regular question about it following the slasher film rules.

SLASHER FILM RULES - A Nightmare on Elm Street

A Nightmare on Elm Street, the first film in one of the big three slasher film franchises.  But does this one follow the slasher film rules?

SLASHER FILM RULES: Silent Night, Deadly Night

1984 saw the release of Silent Night, Deadly Night, not the first Christmas based horror but certainly the most controversial (because, you know, small children who still believe in Santa may be upset to see someone dress as Santa if they're allowed to watch a horror film.  It is not a film about a small group being killed off one-by-one but rather a random killer film.  So does that mean it follows the rules or not?
