Damon adequately fills the confused, action hero role and some climactic stunts are surprising, but fans of the novel seeking more mystery may be disappointed. An early scene of surgery at sea, as a bullet is pulled from Jason’s back, may cause wincing. And one fight gets gruesomely brutal as a pen is stabbed into a man’s hand, and just as graphically pulled out. A kiss leads to taking off Jason’ shirt, but further activity is thankfully left to the imagination. Numerous obscenities, some in German, and a string of strong profanity from Jason’s boss, assault the ears. Frequent and sometimes graphic violence, along with tasteless vocabulary is less than thrilling in “The Bourne Identity.”
