It is explained that subjects under sedation have to be “kicked” into a falling motion in order to wake up, and that this is accomplished by falling in the dream state, such as driving a van over a guardrail into a river. Why couldn’t Fischer alone have been dropped instead of everyone being dropped? Since he is the primary dream vehicle the others enter to plant the idea, wouldn’t his waking have a cascading effect that would wake all the others? This would free the group to deal with the projections instead of sitting comatose in the three levels of Fischer’s subconscious.
I read Nolan spent ten years crafting this Möbiusian script. Perhaps the length of time devoted to a metaphysical quandary is inversely proportional to the quickness which millions of movie viewers with uncover logical inconsistencies.
I give this move two inverted thumbs up. Marion still looking good.
