As for The Exorcist, yes, watch it. I saw it in the cinema in 1998 (the film was effectively banned in the UK for many years), and it's not as scary as its reputation suggests - in fact I felt it was a little slow in some parts. However, there are some good moments, and its success and influence on popular culture are undeniable.

Reports of people fainting or throwing up, and the tag "scariest movie ever", are often linked to horror films for marketing reasons (so die-hard horror fans will go and see the movie "as a challenge"). Such films generally turn out to be over-rated: see Silence of the Lambs, The Blair Witch Project, and most recently Frozen.
