Looking at opening title sequnce in film- the Happening

The main function of thriller opening title sequences is that it needs to have the devices to hook and hold it’s audience.
The Happening is successful at doing this in a number of ways.
In the very beginning the screen in full of clouds that are normal looking for a sunny day, the music matches this imagery by being not to sinister but being slow and with an almost classical tune, but tension and suspense is built within the audience as the scene goes on. The clouds start to darken and so does the sky surrounding them suggesting the day wearing on and a storm coming. By the clouds darkening it shows rain or a thunderstorm. It signifies to the audience that something is coming.
As the next scene beginnings were met with a casual and usual day out at the park. We know it’s a usual day in the park because of the techniques used. The lighting is natural sunlight so we know it’s a sunny day and therefore lots of people would be at the park. The sound is natural also, people shouting, talking, laughing, a dog panting as it’s walking. The camera pans out and then zooms in onto two females in the park. The camera angles itself are nothing to intricate because it keeps a completely naturalistic flow and this helps the audience to associate with their surroundings and start to feel ambience again after the cloud scene. The effect of this scene shows normal mundane life, society as normal but it also sets up the enigma that the audience worry about because it makes the audience think they live in a similar society, what’s to stop the antagonist attacking their world. The thought of this thrills the audience making it effective.
In my opinion The Happening is a good opening to a thriller but it does have some faults. It’s good because it hooks the audience, it sets the enigma, introduces the audience to the protagonist and it does thrill it’s audience. By having a high pace it gets to the point which is what a lot of audiences like. However it’s faults is that it ruins connotation by over-doing things, A scene which is suppose to be thriller turns into a comedy.
I have picked up from this opening that I would like to use quite a bit of silence in my own thriller because I think it creates good atmosphere, Also I will try to keep things very subtle instead of using special effects in the way that having people stand still in the happening creates a very thriller look
