Part of the problem is that these huge, epic Old Testament events really only add up to a few sentences, so anything as ambitious as a motion picture (or, at least, one which lasts more than five or ten minutes, tops) will necessarily have more filler, more artistic license, more personal interpretations and more sheer, extra-biblical invention than anything else. There's simply no way around it. Even if someone was aiming to make a film which was totally respectful of the original narrative, there would have to be so much more invented material than anything pulled directly from the source that there would always be bits bound to offend, anger or confuse certain people.
I'm not a huge fan of theses epic type movies in any case, but I don't particularly see where treating the story as basically a piece of mythology in the same vein as anything pulled from the Greek, Roman, Norse or Egyptian pantheons (for example) would make it less entertaining just because it's (apparently pretty loosely) based on a story which most of us were probably presented with as though it was true at some point. Plus, if it does end up painting Biblegod in a less-than-favorable light, it will be amusing to see the backlash.
Anyway, I notice that Anthony Hopkins is in it, and since I've been pretty much in love with him for the past 40 years, I might give it a watch.
