The Bourne Legacy (Blu-ray release 2012-12-11) is the 4th movie in the Bourne movie series. I find it ridiculous that the character mentioned in the title is not in the movie. Ignoring that, I think that most of the movie is satisfactory in terms of setup, plot and action, until the climax arrives.
When it finished a car chase, the movie ends abruptly, without resolving anything. Only after that did I realize the car chase was supposed to be the climax. I think this is really underwhelming for an action movie.
