There's that sort of omnipresent voice over by Don LaFontaine that suits them so perfectly. The constant cross-referencing - The Faculty trailer even includes scenes from Scream! - and the way they all seem to mention rules or have jokes about horror movies (Scream brought many things in vogue, didn't it?) So much fun to watch if, like me, these were the movies you actually grew up watching. Desperately begging a parental to take you and your mates (before shunning them to the back of the cinema, naturally) and thinking you were so cool for seeing an MA15+ rated film that features Tara Reid get butchered while in her underwear (clearly the latter aspect of that moment was a bit lost on me).
Speaking of The Faculty, I had forgotten what a great cast that movie had! Piper Laurie, Bebe Neuwirth, Robert Patrick, Salma Hayek, Famke Janssen, Jon Stewart, Clea DuVall, Elijah Wood, Christopher McDonald and Josh Hartnett. Nowadays the biggest cast member would be someone from The Hills plus a bunch of too-pretty nobodies who nobody will ever see again. Seemingly gone are the days when someone like Anne Heche would show up in I Know What You Did Last Summer! :/
And now I have the overwhelming desire to watch them all.
