After watching Bandersnatch I think that it is safe to say that it was a very ambitious project with a clear artistic vision. It is clear how the interactive film achieved a lot of success. It makes it feel as if there is a real outcome to your decision, this weight makes the audience stop and think about the choices they have to make in fear of making the wrong call.
Letting the audience have partial influence over the outcomes in the story is a good way to engage the viewer to keep them hooked in the moment. This is something that many video games- more specifically, story games do to keep the player entertained. The more entertainment the media offers will directly impact the amount of time the player base spends. Games such as Red Dead Redemption, Skyrim, Fallout, and especially Telltale games like The Walking Dead have their audience in the palm of their hand, clocking in countless hours in each play session.
As for interactive cinema or the Bandersnatch style of film, I do not think that it is the future of film. I think there is a separate industry away from traditional cinema and video games where it resides as its own genre of media. I do, however, believe that interactive cinema will continue to evolve in the future.
