Aaron's legacy (like that of Jason Bourne's), as it turns out, is being considered disposable by the US government, as well as its pharma industry evil twin, in this case Sterisyn-Morlanta. Meanwhile, in a Sterisyn-Morlanta lab, scientist Marta Shearing (Rachel Weisz), who has crossed paths with Cross on more than one occasion, finds herself under attack. Fellow scientist Dr. Foite (Zeljko Ivanek) shoots up the lab, killing six, with Shearing as the lone survivor. The event brings her unwanted attention from evil government agents, but Aaron arrives in time to save her. And so begins their journey, which takes them all the way to Manila so that Marta can attempt to "viral out" Aaron.
Helmed by Tony ("Michael Clayton") Gilroy, who also wrote the screenplays for the three previous films in the Bourne series, "The Bourne Legacy" is slightly weighed down by too much globe-hopping set-up interwoven with flashbacks and extended chase scenes. The chemistry between Renner and Weisz is also lacking, considering the way things end (nope, not giving anything away). Alternating between exhilaration and exhaustion, the best part of "The Bourne Legacy" is the promise of sequels where the details can be fine-tuned or genetically modified, whatever the case may be.
