It is wonderfully discomforting. Do note that, like "The Last Temptation of Jesus Christ", literalists, may care more for fidelity to what is written than to what the story says. With Noah, because Genesis is so awfully spotty about any details, artistic license may not be such a grand sin. On those notes, Genesis has all 3 of Noah's sons and wives on the ark, while the movie has the youngest too young and the second without a mate and ticked off at his dad. The sci-fi creatures, "the Watchers" are also quite a stretch from the bible. Just making Anthony Hopkins a cool Methuselah was worth the stretch. Tubal Cain gets to be a really bad guy while Genesis has him as a clever materialist and inventor sort.
But the movie is, no kidding, unreserved in being pro-life and pro-vegetarian. That would get at least 2 more stars from me no matter how awful it might have been otherwise. But it isn't awful in the least, and very well done, and seeing Hermione Granger in yet another great movie was just added attraction. I am a pro-life vegetarian, myself.
Also, because Genesis is rather spotty--how did Noah keep all the other folks around from storming the ark when the rains come; how did he gather the animals, how do you manage a floating zoo--the movie proposes some ideas.
So, if you want some very good entertainment that might be a bit educational and which might open your eyes to some other ways God might have intended us to live, watch it. Please, watch it.
