I remember seeing the Exorcist when it got rereleased in the theater's as "the Version you have never seen" Someone stood up and said "this sucks" and walked out with his friends. I was sort shocked but then thought.... How would I feel about this film had I not seen it so many years ago? My reaction may have been like his or yours.
Having seen the Exorcist way back when..... I think I was 13 (42 now) the films got under my skin.... Also touched my religious beliefs. The Crucifix scene still gets under my skin. However with time I actually like everything in the Exorcist leading up to the final Exorcism (the boring stuff
) much more then the final Exorcism which I find too over the top.
My issue with the Conjuring may have had something to do with it being a Witch that was the big baddie. Had it been just a demon or demons it would have got under my skin. I did not care for the Witch idea and did not like her goofy over done look (again just things that took me out of the film). Of course it would have just been The Amityville Horror in a different house... So I can see why it went a different path. HAd they not shown the witch I think I would have liked it better also.
I love the Scene where the young girl is pointing at the door saying there is someone there. That whole scene is great.
I think I am coming across as not liking this film at all. I did. I like the cast, I liked the overall look and feel. I just did not like those moments that took me out of the film.
PS - Have you watched the Exorcist again since being disappointed the first time.... You may enjoy it more now that it is not built up in your head so much. Really I don't see how it's anymore boring then the Conjuring and I mean that in a good way.
