I remember several bad movies reviews would bring up bad movie laws. The most frequent mentioning comes from Ken Begg of Jabootu and Liz of 'And you Call Yourself a Scientist' and it's the 'Jason Vorhees teleportation.'
Is there one called the 'Aliens' syndrome? Where if you have one alien it's a killing machine (Alien, Alien 3), but if you have a bunch they go down quickly (Aliens, Alien Res, AvP.)
I'm wondering how reconized these are.
