Get ready for Jasina Bourne, except not as good as Jason.
This is a run-of-the-mill action/spy movie staring Angelina Jolie as Evelyn Salt, a CIA agent with a mysterious past. It was gimmicky action, with attempts at doing what no other movie had done, something that's become cliche in its attempt to avoid cliches. The worst was Salt using a taser to make someone press the gas pedal on a police car - it was just too ridiculous to keep a viewer watching without rolling their eyes.
I really have nothing more to say about this one. It's just not worth your time. I am glad that I saw it on cheap night, otherwise, I would have felt ripped off completely.
