Amanda Scherker has a very funny piece on Huffington Post about the way that changes in technology make it hard to understand what the big deal is in a lot of movie classics. Is it possible to be terrified by “Blair Witch Project” when it seems so obvious they could have found their way home with GPS or called for help on a cell phone? Would the kids in “The Breakfast Club” talked to each other if they could have been texting their friends? And would “Psycho’s” Marion Crane ever stopped at the Bates Motel if she’d checked Yelp?
