I just watched "One hour photo" in order to better research how a thriller works
I was interested at how the film begins at the ending.
The narrative throughout was very interesting and helped to keep the film in motion
I noticed that whenever Si was narrating or just walking around his own little "theme tune" would play, this really helped to draw me in.
The music was very atmospheric throughout and really helped to set the mood, it also seemed to scale with Si's emotional state, getting faster and more erratic when he was emotionally compromised.
there was a shot that was used a lot during the course of the play where Si would be walking towards the camera while the camera backs away at his pace. This was an effective shot on all occasions as it allowed you to look at his face and read his thoughts while he was on the move.
An instance of this that was particularly effective was when he was walking through the store, and the ambient, diagetic music that they played in the store suddenly blended with a more sinister, non diagetic theme as Si's expression turned from a resigned good humour to a dark, purposeful stare.
A good thing about this film was that it really lets the viewer think. It makes you wonder why Si is the way he is and there are hints dropped later in the film about his past but there's no conclusive evidence. This leaves the audience to find closure by using their imagination, combining Si's actions with the subtle hints of what went on earlier in his life.
Overall I thought it was a brilliant film, dark, creepy and thought provoking. A brilliant example of a modern thriller.
