Looking back over the scenes listed and detailed so far, it strikes me that there's a similarity amongst most of them. It seems as if to produce "awe" most folks need to see huge numbers in larger-than-life situations. And that is more than understandable.
Does anyone have one of these "moments of pure awe" which are not of that variety? The reveal of the NCC-1701-A in the early portion of "Star Trek: The Motion Picture" might just be one of them. It certainly is an awe-inspiring kind of moment for me, seeing a long lost love for the first time in many years. But is it possible to be awed so much by more quiet moments?
How about near the end of Children of Men, where the soldiers who seconds ago had been fighting, all stop when the sound of a baby crying crack the air. All of them stand in awe of it and realize how far more important and amazing it is.
