What I don't seem to grasp is why you're so concerned about tomorrow, and about a series of movies no less.
We're all fans here, but what does it matter how they're viewed 20 years from now? It's only been a little over a YEAR for crying out loud.
Y'all seem to like to speak hypothetically and make these crazy comparisons to fit some "relevance agenda", so let me ask this. 20 years from now, what if "nobody" cares about TDKR (or, sure, the entire Trilogy) except the 4 or 5 people in this very thread? How would that even be measurable? Better yet, why would that be important? They resonate with the folks that like them, correct? So why the hell does it matter if others don't? I don't think anyone on Superherohype/Batman/Batman movies section let's anyone's opinions dictate their own (I certainly try not to). Not supporters, not detractors. Why then, are we concerned about the thoughts of a nameless and faceless populace two decades from now? It makes absolutely no sense to me, especially when some of us might not be around.
As you get older, you'll find that time gets faster and faster and things rapidly change. With attention spans getting shorter (studies have SHOWN this) and entertainment being reflected in the technologies of the time, why would anyone in their right mind want to think 20 years forward where it'll be even worse? Enjoy the here and now, not how well or poorly a movie series (that you may love or hate) will be received decades from now. It seems a little neurotic to me, but then again, it's always been this odd pissing contest where fans of something obsess over little things like trailer watch count, box office numbers, awards i.e. things they have absolutely no stake or money in. It's just emotional attachment. I mean, it's normal to want others to love what you love, but only to a point. No matter what happens, I promise everyone that you'll find atleast one like minded individual that shares your stance and opinion in SOMETHING and you'll be able to discuss all of it's greatness to your hearts content. That's the nature of the internet and these message boards. For now? It's over. There are no more trailers, no more virals, no more speculation, only reflection. All there will ever be is "I like" and "I don't like" (and the occasional pic of behind the scenes info that makes us drool, "I've never seen/heard about that before!").
