The next installment into The Exorcist franchise, The Exorcist: Believer, takes place almost 50 years after the events of the original 1973 film, and a lot has changed in the horror genre in that time span. Movies have gotten scarier, thanks to special effects, advanced makeup and prosthetics, and the ability to push the limits further than ever before. However, many agree that The Exorcist remains one of the most horrific films ever, even in the year 2023. As a result, many expect the upcoming movie won't be able to live up to the original's scary factor.
