The reason why Exodus failed is because it tried to please both the atheists & the bible folks and failed at both. Exodus can be about mass environmental damage due to excessive pride & ego of the pharaohs pushing the limits of constructing vanity projects & over-exploitation of labour and the natural resources. All is fine, rational and consistent until Scott includes the inexplicably supernatural scene where
which is included solely to please the bible purists. The movie looks spectacular & the actors do well with the limited script but Scott's movie is seriously lacking in narrative drive, suspense & drama. They should take the core idea of Exodus story and choose a different setting, genre, period to set the story in. You can do a scifi, action thriller, post-apocalyptic adventures. For example, James Cameron's Terminator has elements of Biblical narratives: the Big War, angels announcing the arrival of the chosen one, the idea of a messiah, John Connor= J.C. = Jesus Christ.
