The people who wrote this film apparently don't think the audience is very smart. They want us to believe that Angelina Jolie who is about five foot four in her bare feet and 100 pounds wringing wet is capable of beating up and shooting about sixty people, crawling around a ten story building on a narrow ledge, jumping from tractor trailer to tractor trailer and climbing down a ten story elevator shaft! Boy she is one tough, ass kicking mama! Some people have said this movie is merely a clone of the Jason Bourne movies (one reviewer waggishly called Salt Jason Bourne with a vagina). However, Jolie makes her role distinctly unique. She holds this movie together with cool intensity that would rival any actor. The plot is convoluted and hard to follow but there is enough action for five movies, so just sit back and enjoy the ride. By the way, for you history lovers, there really was a theory that Lee Harvey Oswald had a Soviet lookalike who was the real killer of JFK and there really is an underground bunker below the White House.
