I never got 'carrie', well I got why she went on the rampage in the book/movie, but the torment campaign waged against her that lit the fuse of her going postal...she wasn't ugly like it was implied, carrie was pretty damn hawt as I remember the movie.
Things I've learned from movies-people who start to worry there is some sort of vicious killer lurking, tend to go poking around in graveyards at night, or down dark flights of stairs into basements when there is a power cut and they are unarmed, or only have a torch trying to see what the vicious monster is, or find the demented knife-wielding psychopath.
Teens having sex usually end up being slaughtered by psychopaths if one is about on the prowl for victims.
The black always has to die first if there is one.
People try and run away after being shot in the leg, stabbing people usually isn't either very painful (being stabbed, rather) nor is it fatal unless in the heart or head/throat if the knife is in the hands of a good guy, but every swing by a psycho killer ends up decapitating their victims, taking arms and legs off, and every stab ends up with a killing.
Nothing good ever happens to lovecraftian cultists, but they worship and summon things that ought not to be summoned anyway despite that the inbound flight from abomination airways inc. is invariably pissed and ALWAYS hungry for flesh and for souls.
When a virus infects a hospital or population and people start vomiting blood, people are careless with their hazmat suits. and that these are the times you should quit your job and get the fuck out.
In fights people can take vastly more punishment than it takes to down even the toughest man and carry on fighting, ignore their autonomic nervous system, and often heal up just fine with just a bandage and something to sterilize the wound in minutes.
People really badly wounded will stop screaming when the person cauterizing the gushing wound left after having a limb cut/ripped off with a red hot piece of metal, or once the complicated fracture they have, when the bones have been forced back into position and splinted, from where they had snapped and ripped their way through somebody's arms, legs, ribcage etc. and can seemingly manage without any pain relief from the most brutal of injuries.
Hideously wounded soldiers determined to fight on to the last often refuse morphine to help them stay alert despite having been blown up, shot to shit or burnt to a crisp and they know they aren't getting out alive, they'll refuse the morphine anyway. (it'd be more likely by far to let you continue to fight and to ignore greater degrees of pain and damage until you die/get killed more thoroughly again, and when your able to move and stand then your not likely to pass out standing up on your feet unless the dose is huge. It is possible but it takes a very large dose of painkillers for a person's individual tolerance level for that to happen; easier by far if sitting, or lying down but if walking or running then it really isn't likely.
Just one 'alien' (as in the things from the alien films, and alien vs predator films) is enough to slaughter an entire starship full of armed men and potentially androids as well, even once they know its there.
When the shit hits the fan, the lights are probably going to go out.
