My wife and I went to see it in the IMAX format having read reviews in the Telegraph. The size of the screen and the enhanced sounds made you feel as if you were there in the thick of it.
It was worth going to see in this format, if only to appreciate the terrifying effect of the Stuka sirens, something that I have never fully appreciated in the normal cinema format. I felt transfixed, helplessly waiting for the bomb to drop.
Just another opinion.
