It was no special movie.
Story tries to be "innovative", but it is not realisitc for a spy movie.
In general, how the story plays out in some scenes is very unrealistic.
Some parts of story were also just gap fillers. For example the husband of lead charackter Angelina Jolie.
My review: Go watch some Jason Bourne, or something like that instead of movie "Salt".
Most heavily hyped movies are rather mediocre - so my expectations were low. Hence, I was pleasantly surprised that the film has a tight plot with a few good twists, and an ending that was the logical denouement. I'm not an Angelina fan, but she did a fine job in the lead role.
Had this strange feeling throughout the movie that it was a remake of something. Lots of action but really...some far fetched scenerios like the one with the President of Russia. Overall it was something to watch and enjoy even.
