I saw NOAH last week and thought it was laughable! Actually the biblical account of Noah is a pretty good story: they didn't need to mess about with it, omitting God and the other 2 DIL s and adding in ridiculous concrete monsters. As for Noah getting some mad idea about having to murder his grandchild if it turned out to be a girl.....stupid, unnecessary, unbelievable....!
Still, it wasn't the worst film I've seen lately, and it's pretty rare to find any film that has no swearing or turgid sex scenes !
Btw GillT57, yes, mankind was vegetarian (probably not vegan) until after the flood. Of course, the landscape presumably wasn't barren; in the film they were trying to say (I think) that man had spoiled the earth and that's why the pickings were slim!
