yeah, in addition to being a wuss, the blatant continuity errors/ridiculous suspensions of disbelief required kinda get to me with a lot of horror storylines.
"Let's split up so the psycho can bump us off one by one!"
"Right, we've knocked the baddy/psycho over, instead of nicking his gun/machete/weapon and rendering him useless and thus ending the film an hour too early, let's just run away instead"
"Hmmm, this sounds fishy and possibly extremely dangerous, let's not call the cops and instead investigate ourselves without telling anyone where we are and without bringing any weapons to defend ourselves with"
etc. etc.
