A Priest, a Soldier and a Child go into a bar...

Really?
I can't seem to understand how in the world this combo can become a movie blockbuster. Based on 1% reality and 99% lies, like most movies, this one is the story of a Rambo-like self-proclaimed priest who goes into a killing spree to free children. If I got it right, killing is a good thing only if you are doing it under God's commands. Did I get it right?
