Modern Technology and Movie Plots

....Directors have no problem getting an audience to believe in ghosts, vampires, succubi, extraterrestrials, poltergeists, gremlins, wizards, giant worms, latter-day dinosaurs or rustic werewolves who seem to have unlimited access to steroids; all that is deemed perfectly logical and believable. But it is impossible to get anyone to believe that a character in a horror film or thriller would not be armed with the technology needed to foil the depredations of his rampaging, bloodthirsty stepfather. This is the impasse to which technology has brought us.

I read this in an article about how modern technology has affected the plot structure of films and thought it was quite interesting. How so many films would not have the same affect on it's audience if set in today's technologically advanced world. I was impressed with one persons response to the article:    

Taxi Driver,

Rather than mope around his flat bored and lonely Travis would either become an obsessive facebook stalker or use the internet to reach out to likeminded individuals.. in fact that would make a good film in my opinion! the resultant bloodbath would be awesome.. thats if Travis could be bothered to leave his flat rather than getting bogged down in internet porn or spending his days arguing with people on youtube.

Travis Bickle, send friend request?

Can anyone think of any other good examples?

Thanks for reading, Chris.
