I have seen most of these and agree with your assessment on most of them. Have you seen the directors cut of Exorcist? There were some scenes that were removed from the original release because they were deemed too creepy and scary for audiences back when the movie was originally released. On a side note you might want to check your numbering on the films above, since all of them except one of them says "1" next to them in the list. :) I know this isn't your fault and is just a flaw in the editor.
