I saw a video once that explained how modern media is creating silo effects that hinders future shared cultural phenomena. With the separation of media like it is, there are walls that have been created to group movie viewership into smaller swaths of viewers. Cult films historically are liked by people of similar tastes of film. In the past, any movie could be seen by anyone after it went to formats such as vhs or dvd. Single formats mosts people owned. A future films abilities to become "cult fav" are disrupted by the requirement for payment of potentially multiple streaming services. When you impede chances of viewership, you decrease the chance of the cult-like status a movie can develope. So basically, availibility. There will be cult films, but maybe like cult Disney films, cult Netfix films, or cult HBO Max films; ect... "Cult"only to the people who had those particular services. With the reworking of the film distribution industry it will be hard to experience true cult followings for future movies.
