I have to say that there hasn't been a more underwhelming franchise than Mission Impossible. Every movie has a cool set piece or two but they are almost all forgettable. I think one problem is that Ethan Hunt is a pretty bland hero. He showed some signs of life in the last movie because he actually had a backstory with his new wife but even then it wasn't really enough. He's another agent on the job, trying to right a wrong (that has probably wronged him). But the bigger issue is the lack of a cool villain. I can't remember any of the bad guys from Missions Impossible and even the fairly generic nemesis that Chris Cooper played in The Bourne Identity sticks in my head. And after watching this trailer, I don't think that Ghost Protocol has fixed any of these issues. It still seems like a personality-deficient James Bond chasing forgettable enemies.
