Great subject matter with good people doing a difficult and sometimes dangerous job,BUT the voice over ruins it with doom and gloom comments, he is trying to make it more exciting but is totally overdone, the smallest thing could end in "COMPLETE DISASTER!!!" "POSSIBLE DEATH!!" "COLD BE A FIRE!!! And so on, the viewer isn't stupid! A more calm descriptive prose would still present the difficulties and dangers in a less "DRAMATIC!!" way.
