I'll give it a 2-star for the lovely animation and singing. But real quick, why do you feel the need to tell rewrite the Bible?
The Bible makes it clear how Moses left Egypt. And was the scene with Zipporah as a slave necessary?
Now, why was the burning bush in a cave? Didn't the Bible say Moses saw it from afar of?
But I guess what is most disturbing is you start the movie by informing us that what we are about to watch is factual—it's clearly far from it.
