Spoilers for Evil Dead, Trick R Treat, And Aliens
In Evil Dead, they realise the house is haunted and run into the woods. That just makes things worse. They get in the car and try to flee back to civilization. The only bridge has twisted up into a claw like thing leaving them no way back. Also in Evil Dead 3 Army Of Darkness, there’s a fantastic scene where it seems a monster is dead. Somebody is about to casually walk over and poke it. Ash, hero of the first two films, stops him saying “It’s a trick. Get an axe.”
In Trick R Treat, there’s a scene where a monster seems dead. The old man with a gun wants to be sure. So she does a safety shot to its chest and then blows off its weapon hand.
In Aliens, Ripley famously advises “Take off and nuke the site from orbit.” rather than staying and fighting.
