Drexel, that scene certainly proves the power of excellent screen writing, directing, acting, and editing.
Again, I enjoy the film because Friedkin did not leave us guessing nor did he create an illusion of the never-ending horror film as so many others did and continue to do. Friedkin delivered a one-film tribute to the novel without the word “sequel” in mind. The other films stemming from the original are simply ripoffs desperately trying to make a tie to the masterpiece. Personally, I would never try to connect the other films back to the original and fulfilled concept.
