So many mixed feelings about this movie
Yet for some reason, I actually kind of like this movie, and feel the need to defend it, because there are times where I actually prefer this over the original Exorcist. A statement like that may seem like blasphemy(no pun intended) but I actually think that this movie had an interesting concept, just horribly carried out.
I like Richard Burton's dry slow delivery, I know people like to point that out as one of the flaws of the movie, and yes Burton was clearly drunk while filming, but that slow and dry delivery works and blends in well with the pacing and the atmosphere. The surreal visual style and tone is this movie's best strength and IMHO what could have been it's saving grace with a competent director at the helm.
