It dumbs down the movie if you have to explain it. That's pretty much cinema 101. If you aren't good enough to show them, for instance, let's say you're an actor (this is a micro version of it) and you get hit in the leg, if the director tells you to go "OW MY LEG!!!" then you are a bad actor because you can't convey it. It's insulting to be told every theme, no matter how many "smart" words you use (it just seems like intelligent to stupid people), if you have to explain anything it's dumbing down the movie. How is it not? The way Nolan did it might have dumbed it down less but he still dumbed it down.
Gordon's speech at the end is different because it was a closing. However, Batman stating his emotions is dumbing down the movie. In American Psycho he had a running narrative but there were deeper feelings to be revealed by his narrative, so that was smarter. Plus he wasn't saying it to other characters. I use Am Psych and an example because I think it's an amazing movie.
Well again I just disagree. It does nothing to dumb down a movie. In real life people will explain their feelings to others with words, and it does not take away from it if they are feeling it as well.
And you seem to be thinking people are stupid (which is wrong you can think differently, but don't try to put down others to make a point by using terms like dumb it does insinuate towards those that enjoyed it that they are the same. Which is not true) that don't see this as a bad thing. Some of my favorite films are considered pretentious stuff, like Blade Runner, Apocalypse Now, 2001 ect. But to me your post is more degrading because your saying that people are dumb for liking such a way of verbal exposition.
It really does not dumb a movie down, it does help others maybe understand more, but that does not mean they will look at the themes any deeper is the thing. I remember walking out, and many people to this day I talk to don't have the same understanding of the many many themes, subtle and explodes ones.
Like Anita said, these actors did a great job "feeling" things and saying them at the same time. And never did it get extreme almost as your suggesting.
And again I hope your not going into the territory, of its dumbing it down for dumb people, and we are dumb for seeing and appreciating the depth given on both levels, exposed and subtle. That pretentious attitude is not the best to carry around. So I hope you respect how others feel on the matter with out calling them "stupid or dumb".
So no it's not dumbing down, you may not like the expose' of it. But the actors will all top notch. You can strip away the dialogue and they still have the emotion there. I mean hell one of the actors one an academy award for it. A film can explain ideas and themes, and still keep a balance, its a fine one sometimes, but Nolan I believe did it with perfection. More so in TDK.
And you can have your opinion, that is just fine I'm not trying to take it away from ya.
