I think we're on the same page here by the fact you sourced the BvS forums as your primary example.
With all due respect to anyone here who frequently posts there, the BvS forums are practically universally mocked
anywhere you go on the Hype, from the Marvel forums to even the DC television sections. Almost nobody posts there but the fanboys,
not because of the opinions people hold but because of how fascistic they come off in response to those who disagree with them. It's a mixture of MOS fanboys, Nolan haters and extreme Batman fanboys. A minority to a group of nerds, who are a minority in the total population in the first place. That's kinda my point, and why I wouldn't put too much stock in it.
I'm an early 20's guy that hears lots of nerdy things being talked about on a constant basis wherever I go, especially on campuses. I'm already seeing the "GA" go crazy over the Spider-Man announcement in real life. I guess this generation is a bit more nerdier than the previous ones, but the Nolan films are almost never talked about. Now to be fair, neither are the current DC films, or even the Fox films. Marvel seems to have mastered the art of getting people excited and talking while there's nothing out, whereas everything else seems to continue the pattern of trending "in the moment" when it comes to GA hype. The Arkham games are almost always brought up when you're around any sort of gamer, and once in a while you hear a comment every now and then regarding Affleck's take.
So in a way, the Nolan films are definitely an afterthought at this stage, and people seem to be ready to see the "Goddamn Batman" for lack of better words. But if anything, it seems more like a natural progression. Everything builds on top of something else, and the current batch of Marvel/DC films have clearly been built on the TDK trilogy. The train started running that summer in '08 with TDK and Iron Man, the latter having been influenced by Begins. As the years pass, I don't think people will forget that. It wasn't just a case of solely box office influence, it was genuine quality inspiring genuine quality much like Donner's Superman did.
I guess that's my final point. The Nolan films can go either the Burton way or the Donner way, and I think it's much more likely they'll go the Donner way. They may be viewed differently, maybe there'll be totally different reasons to why they're liked, but there will still be an element of sacredness and of "I can see why this had the impact it did" that Burton's franchise had a tougher time carrying forward, imo.
I also appreciate the compliment.
