Real thriller opening

• Music suits the genre
• Titles look creepy and daunting, which is amplified by the daunting music
• Nice camera work. Good shots of city
• At first doesn't really show what is going to happen in film, but then introduces characters straight away
• Name is cool, suggests what film is going to be about, very appropriate.
  
• When the name of the film comes up, the music is at its most dramatic, and then changes to a different pace
• Ironic how the titles suggests an enclosed place, but the beginning shows New York, which is clearly not an enclosed place
• Camera angels help the daunting effect
