Before I say anything else, yes I'm a Christian and yes that perhaps makes me bias here. The fact is, if you are easily offended by anything with a religious edge to it, then give this a miss.
This film has a blatently pro-Christian, bible message to it and about how society needs the word of God to survive. If that is going to frustrate you... its maybe not for you.
Religion aside, you also have a good action flick, with nice fight scenes and some impressive CGI and slick camera work. Although at times, you feel like you are watching an MTV music video, but thats forgiveable.
But anyway... religion, the bible and christianity are at the forefront of this film and I would say it does a good job of promoting God and showing that while some people will abuse his word, others are simply out to make the world better.
