This is a borderline religious movie about The Old Testament, and watching it, I got the same sort of feeling I get watching Christian metal bands, or seeing a couple of religious missionaries approaching the front door.
As a matter of fact the two main characters at the start remind me somewhat of said missionaries or Christian rock singers, with their clean cut, clean living, innocent yet appealing straight jawed features (same goes for 'Road to El Dorado' to a lesser extent). I don't know why, but I just find Dreamworks' character design slightly repellent.
You know what really irritated me about this movie, though, and why, to me, it fails at a fundamental level (no pun intended)? I assume that it was supposed to portray the God of the Old Testament in some sort of vaguely positive light, when for my money he comes away as a mass-murdering, egomaniacal psycopath. Got a problem with the Pharoah? Hit him with a lightning bolt? No, just kill everyone's children. Considering the film is presumably aimed at children, what sort of confused message is it actually instilling? I can't imagine many adults I know who actually thought about this movie coming away from it with a soft spot for Yahweh.
Ok, I said it had some virtues. Well, the animation is always at least good. In the chariot race scene it's quite eye-popping, and - here's where I have to grind my teeth and give credit where credit's due (which is to say, to the art designers) - the 'fresco' scene involving the murder of the first-born slaves being 'brought to life' was a genuine artistic achievement. Actually it was brilliant.
Other than that, it's creepy, hateful, facist, religious garbage.
