Well, maybe he will return again to more low key productions. I also don't appreciate his turn from indie hope to mainstream appointee. In my opinon his remake of Erik Skjolbjaerg's masterful Insomnia (1997) indicated a step into the "wrong" direction (cof course only creatively and not money-wise). Although it was a surprisingly good film with some original moments, the extent to which it copied the original (way too much) wasn't an indication for a creative force behind the project, rather than attempt to cash in on a bankable concept. The ending of the film, although poignant in its own way, was evident proof of the latter, as it shied away from the bleak outlook of Skjoldbjaerg's vision which it had already softened over the course of the film through the exclusion of the most disturbing, but in the original concept ultimately rewarding and essential episodes. 
After his disappointingly mediocre an un-daring take on the Batman franchise I didn't go out of my way (and into a multiplex) to catch The Prestige, although I've read some benevolent reviews from some critics I trust (not to mention many outright enthusiastic reviews by regular moviegoers who were grateful to see something more rewarding than the usual mainstream product).

But who knows, maybe Nolan will try to reassess his position as a foreign filmmaker inside the system in the future, and a creative spark will make him "burn" again
