As the other physician in the movie says herself: Don't try to understand it - but allmost all of the explanation happens right there.
The rest of the story for me is just having the principle run itself in greater and greater circles - and Nolan does a great job of showing the possible implications of that principle throughout the story.
From the point of acting, scenery, image and color, i'd give it even a 10star.
Very much enjoyed it, wil enjoy it watching it again - even if i will watch it again yesterday evening...
