I must issue a small disclaimer in that I am a very big fan of Sofia Coppola, and this will be praising her/her film — if you are not interested in or happen to dislike her films, this might not be your type of post. Thank you!
When it comes to accuracy, even some of the simplest details can prove to be extraordinarily important. In films made in the present day that are supposed to take place a few years prior, one might overlook some of these small details — perhaps they will believe that it doesn’t matter enough, or that something doesn’t change in only a few years. Yet this is entirely not the case — especially in more recent years, and especially with regard to technologies, things change all the time.
