You may have heard there's a film coming out this week that uses the early narrative portions of Exodus as its source material. Given the widespread promotion of the film across every platform known to man, you'd have to be living under a rock not to be aware of it. I've never been a fan of these biblical epics, with perhaps the exception of Ben Hur (1959), a film which only briefly intersects the biblical narrative.
When I was a Christian I would usually lament the lack of fidelity to the source material. Now that I'm not one, I'm mainly not a fan of the genre because the films tend to be either hugely slanted toward religious audiences or stand in some kind of half-way point of being critical while still conforming to the expectations of those same religious audiences because money. I suspect Ridley Scott's film will sit solidly in the latter category, though I'm willing to be proven wrong. I'd like to be able to enjoy these films the way I enjoy films like Clash of the Titans (the Ray Harryhausen version, of course), but until such time as the culture I live in can view Yahweh, Moses and Samson the same way they currently view Zeus, Odysseus and Heracles, I don't think I'm going to be able to truly enjoy a film adaptation of a biblical narrative. That's just me. Your mileage my vary.
The Ridley Scott film has already been criticized for its portrayal of events involving specific ethnic groups without casting people in the principal roles that even remotely resemble folks from those ethnic groups. That will not be what many Christians will criticize, however. I'm going to go ahead and address some criticisms from some in the Christian community. The first is the standard complaint that the film is not faithful to "biblical history." The second is how many will be quite put off by the way the deity is portrayed in the film. Some of the early reviews I've read have mentioned that Yahweh is represented by an eleven-year-old boy and that the decisions and actions of the deity are similarly immature and, to borrow Christian Bale's term, "mercurial."
