Terrible movie

So when Clive discovered an error in what time the guy arrived in Germany, he told his friend while they were together in an office. A little while later, Clive discovers a bug in the guy's home phone. If Clive spoke to the guy via phone, then the bad guys would have heard the conversation via the bug. But they spoke in person,. And the bad guys still found out.
Why was Naomi Watts even in this film? A NY City assistant district attorney getting involved in international intrigue made no sense.
Did the good guys vindicate anoyone? The main banker bad guy was killed by Calvini's man. The assassin was killed by his own team. The Russian advisor was killed by an unknown. If you follow a hero's story for two hours, at least let the hero kill the bad guy at the end. Don't send in some character who we have never seen before to come in and do the deed. What a trainwreck of a movie.
