The Bourne Trilogy

The Bourne Trilogy is composed of The Bourne Identity, The Bourne Supremacy, and The Bourne Ultimatum. While originally books by Robert Ludlum, the first book has been adapted into a miniseries in 1988, which was reasonably true to the book, and a trilogy of movies, directed by Doug Liman (Identity) and Paul Greengrass (Supremacy and Ultimatum). All that the movies have in common with the books are the titles, the bare-bones of the plots, and some character names (and even then, not really).

The Books
The books are completely different in almost every aspect from the movies. Much more focus is put on twisty, convoluted plots that seem like someone stuck eight different books into a blender.

There are two additional books by Eric Van Lustbader, but they are bad because, like a bad fanfic, they disregard all previously-important canon characters except for Bourne. In the interest of completion, however, they will be detailed.

The Movies
Among other things, the movies are responsible for turning Matt Damon into an action star. This is recognized by many as a good thing, but the screaming fangirls that inevitably follow Matt Damon are a bad thing.
