Openings

Done some more research into the Psychological Thriller openings, by doing this I found out quite a fair bit about what the typical elements of these openings are, I looked at a few openings:

The Sixth Sense
We Need To Talk About Kevin
Seven
The Butterfly Effect 3: Revelations
American Psycho
Donnie Darko 
Saw 

I looked at 4 out of the 7 in greater detail because these were the ones that had the most gripping and interesting openings and used key elements like creation of enigma, pace and rhythm, really well:

                                             The Sixth Sense

                                  We Need To Talk about Kevin

                            The Butterfly Effect 3: Revelations 

                                             American Psycho
