Sisko being the Emissary simply because he was the first one to encounter the Prophets and they viewed time as non-linear was perfect. Making him Space Jesus dumbed everything down. Making Dukat the Space Anti-Christ dumbed things even further down.
Agreed. I was okay with the whole Emissary thing right up until he was "born of a Virgin Sarah." I have said it before and I will say it again, I think it would have been more impactful had he chosen
to leave Starfleet and moved to Bajor after the war to "preach the gospel." It would have showed him willingly accepting Bajor as his destiny instead of it being forced on him.
