I saw the first one, The Bourne Identity, the summer of 2002. After that, I decided to read the books. Then, I saw the second movie, The Bourne Supremacy, when it came out in 2004. Anxiously awaiting the release of the third installment. I do have some issues with them changing things from the books (like killing characters off in the movies that don't die in the book, and adding completely new characters that weren't in the book at all), but they do that with lots of adaptations, like they did with Tom Clancy's Jack Ryan novels.
