Just out from it.
This is the Christopher Nolan I've been waiting for since 'Memento'. None of his movies, including 'The Dark Knight' have been able to hold together satisfactorily right through to the end credits without falling down in some department. 'Inception' kicks into another gear in the closing 15 minutes, providing an emotional killer punch that was needed to lift it out of being smart but clinical sci-fi and left me satisfied with just a hint of a 'hang on a minute' moment at the end that allows the movie to live on in my mind, not just as memory of a cinematic experience but as a question that only I can answer, if I choose to.
I thought about half way through it was going to be let down by its clinicalness but the glimpse of the emotional anguish at the heart of the story saved it.
I can't wait to savour it again, maybe in IMAX next time.
