Review of The Hurt Locker

The Hurt Locker. A powerful insight as to what faces the armed forces based in Iraq have to experience.
The plot follows three soldiers belonging to a bomb disposal unit.
What intriqued me was the absense of any indepth plot surrounding the unit.
The Hurt Locker mainly focuses on one key issue...Sergeant First Class William James and his ability to switch off his normal life while defusing IED's, disregarding saftey protocols which left his fellows soldiers bemused.
When asked 'how do you do it?, his reply was...'i dont know'.
Then towards the end of the movie he is pictured with his family, playing with his young son, helping his wife make dinner etc.
The closing scene sees him in his protective gear, walking towards an IED as if he didnt have a care in the world.
I felt the movie left me with this thought...Soldiers can become desensatised by what they see and experience during war...to the point were normality takes a back seat.
Very powerful. Very sad.
