6. Marie - The Bourne Supremacy
How She Died: Jason Bourne's accomplice and eventual lover, Marie, is living with him in India when she is shot in the head as the pair try to flee from an assassin in a car, who was trying to kill Jason.
Why It Sucks: The strangest thing about this one is that it doesn't happen in Robert Ludlum's novel, and is a total departure for the movie. In fact, Marie lives long enough to star in the third book, Ultimatum, from which the movie takes an even more significant step away. Though Paul Greengrass did a great job heightening the intensity of Jason Bourne's adventure, and Marie's death certainly gave him an extra motivation, doesn't it seem a bit cheap and disrespectful to do away with a well-liked literary character so flippantly?
