Maybe, maybe not.
Right now I believe it is 50/50.
As good as Batman Begins was, it was simply how it differed in direction that gave it its "freshness" when it was released.
Now that it ain't so fresh anywhere, if I were to watch it today, I totally cringe at the second half of the film. It felt like an unedited "list of things we have to do" sort of deal where Nolan just pieced together footage to tell a story. Too many quick cuts back and forth with very little transition.
TDK was much better but it had some fat to be trimmed at certain areas. There are some plot holes and I didn't care much for Gordon' faking of his death. It felt too contrived just to add some "character" and melodrama to Gordon. We know that Gordon wouldn't die so early. And what's the deal with the timing of the window curtain? Was it to set up in case Batman arrives or was it to just create a diversion? Again, I might not be the brightest dude on these boards but I think these little mini-subplots and gags just slows down the story.
I also felt they wasted Two Face as well. He is a better character than what they showed on screen. Even though Two Face was written as a "backbone" to TDK, with the way Heath transferred into the Joker and all, I did not care or feel for Two Face's journey even one bit. Aaron Eckhart is a very bland, dry and wide-eyed, two dimension actor (no pun intended). He looks the part perhaps on a poster but when the film is rolling, I thought he was just doing his lines. I thought they could use someone with much more charmisa, someone who is more dramatic and who can actually make me give two bits when his face is about to get blown off. Again, this is just a personal greviance, I don't think many complained about Eckhart other than myself. Either way, I don't think TDK would have been the great ride that it was if Heath was never there and nothing as good or better as his Joker was present. As soon as you take out of the Joker scenes, TDK becomes less of a movie than even Begins.
Now that TDKR will soon arrive, I think it could disappoint if they don't put enough focus on Bruce Wayne and Batman's journey and waste too much time on gunk like water vaporaters, 3D Batman Sonar, hammy CSI bullet-fingerprinting detective sequences (many in the theater did not get, or cared for this).
I also fear that right now we're already sitting on top of a very large amount of characters. You have to do Bane, Catwoman, Gordon, Ras, possibly Talia, and all the other supporting cast justice all while making a thoughtful and meaningful conclusion to Batman's arc. That is a tall order.
And I know this is just preliminary but the set pics aren't shaping up to be all that grand. Batman in the daytime partaking in a massive free-for-all brawl against Bane in a Sabretooth coat? If it fits the story, that scene will look good. But it better fit that story DAMN WELL, because otherwise it'll just look really odd and out of place.
Just a prediction: I believe that Nolan wants to make Bane appear to be Ras's pet project that's gone haywire. Perhaps Bane is someone who Ras thought he could trust to destroy Bruce but ends ballooning out of hand once he reaches Gotham (thus setting up a LoS/Bane/Batman triangle).
