I agree. A straight up modern remake of The Godfather would be a disaster. I can see some hack like Brett Ratner getting his hands on it and thinking that he's actually improving on the original film. Then they'd set it in Tokyo and cast Jackie Chan as Luca Brasi and Chris Tucker as Michael.

However, tweaking with the setting, but keeping the overall plot and theme of the movies intrigues me. Especially the feudal Japan one. That could be awesome. Plus it would be so different it wouldn't even resemble or feel like a Godfather movie. We'd just be watching and picking up on various plot points and themes.

I'd be smiling as I was doing that too. Most people here would too.
