You could argue that Prometheus doesn't provide any new material over what the history channel provided on the same topic.
Ridley Scott is 77 years old. This may just be an organic decline in his creative aptitude.
As bad as Exodus may be, directing that project at age 76 is impressive.
But again while flawed, Prometheus challenged me as a viewer to imagine this race of aliens that may be our Gods. It captured my imagination. I guess this was more a passion project while Exodus was what his bosses wanted out of him.
Would have been interesting for example to have Moses and this whole story being about a war of multiple Gods. You have a God that has chosen a people to be protected at all cost, they are his chosen ones but they are enslaved and beaten so he ruins the kingdom of the Leader that does this. But when it's all over, you see that Ramses is alone and does not have much of anything. And then you see his own God coming down. And then you learn that this God gave the Egyptians all the knowledge that they possessed and he gave them their abilities. So he appears and is pissed off that it's all destroyed and you could see a war of multiple Gods. You also learn that these Gods have a sort of vampiring nature wheras they choose a race or tribe of people and their worship gives these Gods their powers.
