This seems a damn good discussion to have, it just doesn't fit where it was posted, so now it's here!I think - and this is probably a subject for another thread - that a lot of horror really suffers in today's world. Many horror plots unravel entirely when presented with modern technology.
(For example, "find the last known location of the victim's phone via Google Location History," done.)
For my money, horror plots unravel entirely when presented with technology in general, to various degrees. The point of horror is to make the schlubs involved helpless, isolated and ignorant, and technology does a pretty good job at lessening those - which is why we keep it around. Generally, horror stories respond by just making it not work.
Say it with me now:
The monster is bulletproof, because of course it is.
The phones are out, because of course they are.
The car won't start, because of course it won't.
The power went out, because of course it did.
Flashlights last about five minutes, because of course they do.
"There's an awfully convenient lack of wireless reception" hasn't quite graduated from "bullshit excuse" to "genre convention", but give it time.
