Nolan strives to keep a theme to his movies that convey a sense of being iconic. This always needs the presence of idea to found the film that will conflict with the viewer's mind. Examples are time-discontinuity in Memento. If you break it down, none of Nolan's films are actually that complex when you take a step back. It's the manner in which they are told, and the questions he can pose using certain formats (Memento and Inception being the best examples here) that make them so interesting and incredible. Works better with actors than the set what i mean is that there is no doubt that The Dark Knight, Inception and The Dark Knight Rises have stunning set pieces, but the characters are the core of it. All of his films to date have focused on some sort of obsessive tendencies of characters and how it affects those around them and that is another talent that Chris has. He wants his audiences to consistently impute that they are looking at something larger than life and this is where all the previous points I made tie in through the amazing filmmaker that is Nolan. The characters he presents to us are deep and well thought out to the tiniest detail. The fact that they are major players in industry even in small roles Nolan makes us believe even more in the fact that we're watching something special. There are no details that are too small to be tied together in his projects.
This is the world of Christopher Nolan and in time more will understand it. But till than people can continue to use the word "fanboy" to describe his fans lol.
