Okay, so let’s deal with the biggest failing first. Even when the film was written in the late 1980s, the writers completely failed to predict the internet.

Throughout the futuristic sections of the movie, fax machines churn out paper – in one instance to tell Marty he’s fired, and there’s a reference to the latest innovation of ‘dust-repellant’ paper.
