10 Smartest Horror Movie Decisions (That Still Got People Killed)

Splinter sees a strange parasitic fungus take a hold of life forms to crumple them up like wet tissue paper and pump them full of the titular splinters, possessing those it kills to turn them into fleshy marionettes with a knack for contortion. It's very icky, very cringe-inducing, and very, very messy.

It turns out, however, that this horrifying mushroom can be avoided by lowering one's body temperature, since it attacks the warmest thing it can find. Seth - trapped in a petrol station and penned in by bodies, and body parts that have been overcome with the stuff - packs himself with ice to sneak past the creatures, outsmarting the monstrous mould to get to a nearby police car to call for help.

Only, he didn't plan on not being able to use the car radio without its keys. Another trapped petrol station dweller, Dennis, has to distract the creature as Seth's body temperature rises to dangerously visible levels, causing the infected monster to get inside the shop. Whilst Seth does get a shotgun and enables the escape of his peers eventually - Dennis remains behind to make sure the splinter monsters are destroyed since no-one else is coming.

Whilst the ice get-away was incredibly well-considered, a blip in the original rescue plan resulted in a new direction, and death for Dennis.
