first thing you notice about this opening is the really good use of credits. The credits are built in to the surroundings e.g. the main title is written across the gun. However, the credits were quite difficult to read as they were put across quickly and were in quite a hard font to read.

I felt the non-diegetic music did not relate to the theme as it was a bit up beat and happy for the thriller theme however the diegetic sounds of breathing and footsteps and the gun were used effectively.
the camera angles and editing are good as the film flows and is not jumpy as well as a variety of shots and angles creating an overall good opening
