I agree with the "no plot" criticism, especially today w/ every part of a war being filmed, written about and covered. If you want to see a "documentary-type" movie you can usually just see a documentary.
I do respect her in theory for trying to make a movie that goes against the typical structure of a Hollywood movie, but at the same time, I don't think showing 3 tense, bomb-defusing scenes really adds anything to the first one shown.
Whoever the actor is who played the main guy was really good though. I wouldn't argue if he won an award.
