I watched Noah the movie. I was quite impressed. I am a Christian and I found this movie to be one of the best biblical adaptions I've seen. It does not follow the story of Noah exactly...although there's barely anything written on the Ark story so they only add to that for the vast majority of the film....but it follows the essence of the story, and shows the essence of well...the entire Bible.
So spoilers ( duh ). Also religious discussion because DUH Biblical Movie.
God is portrayed...pretty well actually; He is on neither the extreme end that many people think Him as being these days: Either asthis evil meglomaniac who doesn't give a shit about humans and/or who actively punishes them in horrific ways for defying His will or as this purely benevolent being of light who does no wrong.
He is portrayed as a being who gives humanity free will, the greatest gift we got from Him, and someone who respects their choices regardless of whether they are good or bad. However that means humans have to own up to them and it's not His job to clean up our mess that we created. although He does it anyway. At one point the main antagonist, who is fairly well written, spits on God for not helping humanity survive in the wasteland that Earth has become with little food, few trees and very few animals....except that the wasteland was made by humans. It's mentioned how Earth was this rich planet teeming with life before humans destroyed it.
So on one end of the spectrum you have the story telling you: You want to not believe in God, you don't want to give about his will and then you want to take the piss on the planet He gave you? Fine go ahead, but He will force you to deal with the consequences. The flood in this movie isn't a method of destroying the Earth, since that was pretty much done, but rather saving it from complete destruction. Saving the few remaining animals from being killed and eaten by the humans.
On the other end of the spectrum the movie warns about the dangers of blind obedience in what men perceive is God's will. God warns Noah about the flood and gives him the tools to survive it and save his species and all others, but that's all he does. Noah however thinks that God wants for humanity to be wiped out, even though there's nothing towards this conclusion besides Noah blind faith into what he thinks is God's will.
So Noah decides to leave the other humans to die because of his perception, he decides to kill of his own granddaughters to exterminate the human race. His own fanatic devotion blinds him to the truth and he's really very similar with the antagonist, just at the other end of the spectrum. Only at the very end of the movie does Noah realize his own mistake and stops just before wiping out humanity.
The irony of the movie is that the director is an atheist, and yet it's pretty faithful to the lessons of the Bible: Yes God created us but He's not going to control us or take care of us every step of the way. He will intervene when necessary but we also have to take care of ourselves. We have the ability to make choices without his interference but we must also deal with the consequences of those choices, and those consequences come every single time and He will not save us from our destruction if it comes to that.
It's ultimately a lesson in human empowerment, sin, free will, obedience and the dangers that come from blind obedience as well as a lesson in the dangers of the human arrogance and that if we push it too far in our hubris we will pay the price, not because some divine being struck us down but because we would have destroyed ourselves. It's a thought provoking movie done with a great deal of respect towards the source material with brilliant acting and good visuals.
I highly recommend it.
