Always a tough list to make with Nolan's great filmography, and probably the only thing in my list that is drastically different from most is my placement of Following and TDKR. Always had a big affinity for Following since I saw it the first time a few months ago, and was blown away with what little resources Nolan had considering it was his first film. It's not a better film per se over TDKR, but considering what little resources Nolan had and that it was his first film he ever made, I tend to hold it in high regard.
