it seems bizarre to doubt such an event(s); it's not something on a scale that hoaxers could pull off, the expenditure was vast, manpower involved huge, and all done in full public view of the entire world on live TV. It would probably be easier to go to the Moon than repeatedly stage a hoax on such a vast scale and get away with it. I think doubters need to look inwards, because their doubts should be telling them something disturbing about themselves.
