TDK is just a freaking electric movie, man. There is a specific energy that film captured that is frankly to this day, hard for me to really put into words. It's not something that can be recreated. 'Topped' is a different discussion, and that's where it gets more subjective IMO.
That doesn't mean its flawless, and by the sounds of it, neither is The Batman. I think TDK's status is well-deserved, and it will/should continue to be celebrated years from now.
The whole idea of it being "better in people's memory than it actually is"....I actually take issue with that. Because to me, the best films are the ones that live on and take that kind of a hold in your mind. That initial viewing experience leaves an impression on you that you can never quite shake off. And Nolan is an exceptional filmmaker precisely because of his ability to construct films that do just that. That is the magic of cinema. Sure, you can go back and pick apart some flaws in retrospect. But you really, really can do that for just about any movie. Especially movies that you watch over and over and over.
