"The Bourne Supremacy" is not quite as good as the other two in the series in my view. It lacks the narrative strength of the first film (the best of the series) and it lacks the visceral action (and clever storyline) of the third film - except perhaps in the final car chase. "The Bourne Supremacy" has a fairly simple structure and is essentially a fast-paced chase movie - find Marie's killer. Nevertheless, it is very tense and enjoyable. I had to watch it twice to get the story (someone's stolen money from the CIA and Bourne is framed to distract attention from the real perpetrator), so you need to pay attention throughout. My only complaint is that Bourne (who is described in the first film as "invisible") is so easy to spot: he makes no attempt to disguise his appearance or even wear a hat. Consequently, he ends up getting chased several times after being spotted on the street or on CCTV. However, as thrillers go this is really good - it's just that the other two films in the series are even better !. You do need to watch the first film to get to know the characters before watching this.
