First of all, I am a Jew who has read the Torah and knows the story of Moses very well. Second, I am a big fan of the original movie which does the actual story of Moses justice. This musical changes things in extremely unnecessary and convoluted ways. At one point the pharoah Ramses makes a deal with Moses that he will free the slaves if Moses joins him. Moses agrees to this. This is an absurd change considering in the original story Ramses hardens his heart and doesn't free the slaves so he can keep his kingdom strong. He also promised his dying father, Seti, that he will not be the weak link in the chain. In the musical Ramses goes back on his word to Moses and keeps the Hebrews enslaved which also makes him a liar and a coward. At the end of the show Ramses survives and is all buddy buddy with Moses. Moses also doesn't even go to the top of Mount Sinai and get the Ten Commandments which is literally the most important part to the story. The production and additional music were nice but nowhere near enough to save this travesty.
