This is pretty much the reaction Nolan was going for.
I wrote in June of 2010:
"A madly ambitious story, director Christopher Nolan's follow-up to The Dark Knight is very much concerned with the metaphysics of dreams. For close to two and a half hours, we get ideas spun at us faster than a spinning totem and are forced to schedule a re-watch to better understand Nolan's creative world. The final image will surely become one of the great ones in movie history."
