Interesting thread.
All the things that 'shocked' about The Exorcist have been used, referenced and spoofed since. The modern audience cannot see it in context.
I was expecting it to be dreadful when I watched it last night. I was surprised actually. It had a good, beautifully filmed and put together 'run up' which took it's time. And I found it hauntingly disturbing.
elena - the poster who talked about how people were more religious then has got it a bit wrong I think.
Actually the attitude that religion was a sort of 'cultural' thing was strong, but many were much more heavily into rationality and science. The space age was upon us etc. And religion was seen as totally unglamorous.
The attitude of the mother in the film was a common one and the rise of psychology and psychiatry etc. meant that we didn't even see 'spirituality' or 'holistic and new age' stuff as in any way credible either.
The priest who didn't understand about exorcism etc. Now, that is long gone, everyone knows about demons etc. and exorcism and ghosts are taken more seriously in popular culture.
It was after this that a huge rash of 'supernatural' stuff appeared in film and now it is everywhere.
I enjoyed the film. It was pretty faithful to the book, good, understated performances.
The effects mean little to me to be honest.
