It has some strengths and weaknesses (***Spoilers***)

Rating: 7/10 (13 August 2012)

but I liked it. It's not perfect but it fits in with the other three Bourne movies just fine. I didn't think any of them were perfect, either. In some ways, this one is superior to the others.
Certain conventions used; for example, the explanation of the science could have been done slightly differently although of course it was needed.
Locales selected were brilliant. Scenery in the Alaskan wilderness appeared to be digitally enhanced. If not, cinematographer deserves an Oscar for this movie. Acting and dialog were first-rate except maybe the scene where she is explaining the science to the experiment. She sure makes the thing she loves sound like a J.O.B., there.
I love a chase scene as much as anyone. Parts of this one were great. Without giving away specifics the need to make the greatest chase scene of all times appears to be irresistible to directors. Manila was perfect for it, though.
It's a good piece of work and I am certain no one associated with it has any doubts.
