Terry. you've sold it to me. I will be going.
I agree with your comments about CGI. I think if a nuclear explosion occurred within sight now it would be dismissed as unrealistic. We have been so inured by big bangs, splattering blood and the like that excellent non-computerised film making has been devalued. CGI has it's place but your observation is so true, the key is restraint.
It can be compared to public speaking. Many feel that the key to emphasis is to speak faster and louder until blood vessels are popping. Give me the contrast of the quiet pause followed by an almost whispered truth. Power is in restraint.
