I think it's funny how we'll discount criticism and age for TDKR or the Trilogy as a whole with, Blade Runner, The Thing, etc. comparison/analogies. Those movies were panned right out the door. It played out completely different than how these Batman movies have. Batman movies were never cult films that took years to have an appreciation for, they've been loved right from the get go for the most part, some even before their theatrical debut. Batman movies have always had that magical aura to them, even Batman and Robin until that fateful weekend. Was there that doubt in 2003/'04 with Begins? Sure, but that was swept away even though the film itself wasn't majorly hyped. It's apples and oranges.
In my eye's I think it's the younger generation, those folks that are in their teens and 20s that are trying to build it up as this Star Wars type thing and make it have more meaning than it actually does. I see it brought up again and again, but it's simply not the case. To appreciate Star Wars, you had to be there. People take it for granted now, but it was truly a phenomenon at the time. These Batman movies, as great as they are, aren't that (which isn't a bad thing). It's something else.
Star Wars, and it's ilk (I'd throw Robocop, Terminator and Batman '89 in there as well, pretty much those great 70s, 80s blockbusters) were made out of humble beginnings and aren't so easily replicated. If you want to see an example, just look at the making of documentary specials. Nobody in the 70s thought Star Wars was going to be "a thing". It had huge problems, a stressed out director (on the verge of a heart attack), and a cast and crew that thought they were making this silly, weird thing. The Terminator? It had huge struggles. Nobody could have imagined this B-movie looking film would have franchise potential. Batman '89? Huge, huge risk. A project few people had faith in from the get go (other than it's crazy producers). They wore their faults and blemishes like a badge and there was a significant struggle to get them on screen.
The Nolan series? Not so. Look no further than Fire Rises documentary. It has great insight but it's crazy pretentious. There's actually a segment that talks about it's legacy as if it's decades years old. The producers say straight up that they had no qualms about it from the get go. It's always been "good", "great", "fantastic" and even the creators say as much. Now I'm not saying this is a bad thing, but it is different.
Personally, if there's going to be one that's celebrated and cherished, one that will age like a "fine wine" (whatever that means for a movie), it's going to be The Dark Knight without a doubt. It's the best thing to come out of the genre in the past 20 years. Ledger's fantastic portrayal of the Joker alone and all the nostalgia the film brings in general makes that a sure bet. As far as "Nolan Batman", "TDKT" goes, Begins was small potatoes back in 2005. It was good no doubt, but there wasn't this electrifying renowned quality to the franchise until The Dark Knight. That era of good feelings is all the Dark Knight, and that was pretty much out of the gate, and for good reason.
There's no denying their impact, but a little bit of criticisms particularly at ONE film out of the three and it just seems like people instantly want to proclaim it as untouchable for the future. From my experience (I was there for those older films that are deemed "classic" now), my money is on The Dark Knight, not the others. Whatever "stand the test of time" actually means. There will always be someone out there with a varying view or folks that just don't give a damn. I think we as a community (fanboys, film enthusiasts, etc.) get a little ostentatious about the things we enjoy, to the point where it's almost ridiculous. Settle down and like what you like, don't worry about how things will play out in the future or how others feel about what you dig and cherish. People can't dictate what you like. It doesn't matter.
