I'm not sure why anyone expected Hollywood to hew in any way close to the Bible, or to any story they crib from. What most annoys is that Hollywood can't just let a good story tell itself. I would think you'd have all the elements of a good film right there in Genesis. You have a man who feels called to follow a strange path, though it makes no sense to anyone else. You have three sons and four wives (Noah's wife, and his daughters-in-law) who, whether by choice or necessity, are drawn into it. Do they understand and sympathize, or do they feel put upon or oppressed by their family obligations? Then, of course, you have the whole building a massive ship thing, the animals, the deluge, the whole world drowning, the finding of dry land, the rainbow. You could even include the Noachide laws, and/or the curse on Canaan, if you can fit those in. You could end with the building of Babel, if you wanted to go out on a somber note. But, no, the director must share with us his VISION.
It was kinda cool that they included Methuselah. He died right at the time of the flood (perhaps in the flood), but most folks miss that.
Isaac Asimov had a pretty good analysis of the engineering problems of the Ark event in his book, "Asimov's Guide to The Bible."
Somehow, I doubt that.
