Cell phones, surveillance cameras, cameras in general. It's fucked up all horror movies. Imagine how quick Chucky would be over if he was caught on a nanny cam walking around doing stupid shit. What else? How quick you'd be able to call for help with fucking one of the people from Scream attacking you. Which for whatever reason they always. Their phones always work. But I don't know. Anywho, technology is my biggest pet peeve to find in horror movies
