Query: What a horrifying waste of time

This movie bore absolutely no similarity to the book. The casting was horrid; there was zero chemistry between Matt Damon and what's-her-name, and the ages were all wrong. I seriously doubt if the screenwriters have read any of Ludlum's work, let alone "The Bourne Identity." Do yourself a favor and read the book instead. The story line is brilliant and exciting, not at all like the mind-numbing tripe of this film.
