Yup, Nolan being a perfectionist has always been a misconception. He likes to work fast. There's a reason his movie often finish early and under budget. But ironically I think his style gives his movies an organic, human touch (I say ironic because he's always accused of being cold). Fincher, on the other hand is the very definition of cold (I love Fincher's movies too though). I'm pretty sure Nolan actually likes the little imperfections.
I think the reason Nolan is able to work like this and isn't some Ed Wood hack (although there are some haters who would claim he is), is because he really does have a very clear vision of what he wants on every level, he's able to assemble amazing casts that are eager to do good work for him, and they come to set ready to crush it. At least half of directing is casting, and Nolan has one of the best eyes for it out there.
The thing is, every director's style has some drawbacks. Even Fincher, sometimes his movies feel too perfect for me, and it's almost kind of sterile in its perfection. There's a certain blood splattery shot in Gone Girl (don't want to spoil it) that they shot 36 times. 35 times the set had to be completely changed/cleaned. That is insane, and arguably overindulgent.
The wonkiness in some of the TDKR fight scenes, I think, are just a combination of hand to hand combat scenes not being Nolan's strong suit and him probably being okay with it in the edit, assuming most people won't notice (and to an extent he's right- obviously he wasn't concerned with fanboys making gifs, lol). In general, I feel like TDKR must have been a pretty grueling shoot, cause they shot it in about the same time span as BB and TDK but it's the longest movie and has the biggest action beats. Contrary to people who think Nolan just phoned it in, I think he simply applied his same methodology that's been so successful for him in the past and because of the sheer size of the project and length of the movie, more of the cracks showed.
I think of it like music. Some bands play to a click track, and have everything cut up perfectly in Pro Tools to eliminate any mistakes, all the vocals get autotuned, etc. And then other bands do live takes, leave the little mistakes in, keep it feeling raw, etc. Nolan's "band" is definitely more the latter, and I think on set a lot of the time it's more like improv jazz. It takes very sharp instincts to work that way and turn out masterful work most of the time, and that's why a lot of his "editing" is done on the script level.
