You are right. They haven't used the same lights, and lenses.

But if they did, you would be fooled. They don't so, it looks similar--but not the same. This is not a limit of digital optics. This is a practical limit of how far people are going to go to faithful recapture that. And the answer is: not far enough. But if they wanted to, they could.

Also: yes, that sucks that "star wars" might be thought of a "flat" or "blurry". But does it not bother you that Nosferatu and Sunrise are thought of as "silent" and "black and white"? If not, then it should. Otherwise you are calling the kettle black. Change sometimes is a bitch. But hey, fucking Star Wars is now called A New Hope, so we should be well adjusted to that.
