Re: Color Corrected Bluray for Batman Begins??
The films look dissimilar on purpose. The same reason Gotham in BB looks slightly futuristic and almost comic booky in its overt grunge and grime, whereas TDK's Gotham looked like a regular metropolis.
And the Matrix was most likely modified because that's how it was intended to look but they didn't have the means to do it.
Alan Moore on comics:
They've lost a lot of their original innocence, and they can't get that back. And, they're stuck, it seems, in this kind of depressive ghetto of grimness and psychosis. I'm not too proud of being the author of that regrettable trend.
