This ones something of a meta-crime for cinemagoers, as it doesnt necessarily damage the experience of anyone else in the movie youre sat in (unless youre sat on the front row with your mobile on full brightness and text clicks on, you fiend). Offenders operate on something of a paradoxical level: instead of watching and paying attention to the story they paid an arm and a leg to see, theyll blurt out plot details and witticisms about a movies events on whatever social media platform they can get their grubby mitts on, much to the chagrin of their friends and followers who havent seen the film yet and dont want some inattentive sod ruining it for them. Not to mention those friends who know what their mates doing is a douche move of the lowest variety.
