My good friend Groucho, yes, that shouldn't stop me, but rationalism is seen through skeptical prism & the very notion of it is being challenged. It's better to be skeptical/cynical (like you, which I envy and get intimidated in equal measures), but never an outright Atheist, positivist, and other ugly -ists one would wish to attribute. Being one among the -ists, one has to exculpate & clarify the stances that might otherwise intimidate certain sections. :)
Coming to "A Matter of Life and Death", love the usage of technicolor, transition to/from B/W, and set design (especially the stairway to Heaven). Jack cardiff's work should be recognized.
