Some potential, but mostly disappointing.

Rating: 5/10 (15 January 2011)

I'm writing a belated review now only because I'm watching a BluRay version of a better film in the same genre, Tony Scott's Spy Game, and am reminded of how incredible the latter is while Angelina's vehicle here is a muddled mess.
After a 3 min opening sequence where we are introduced to a promising Angelina in a prisoner exchange (sure the director is using torture as a cheap method to create character depth, but that doesn't mean it can't work), the plot flies off the rails. Nonstop action alone does not create people we empathize/sympathize with, unless you're watching a WWE production. If you don't totally lack situational awareness, you should see the convoluted twist ending coming a mile away.
Jolie is capable of more, and with these production values I put the blame on the script writers and director. I can't help but think this should have been placed in the hands of Tony Scott. If you want to see a top notch spy film (possibly one of the best ever), go watch Spy Game with Jolie's better half. As for Salt, you can take a pass.
