My issue with a lot of old scenes was that the scaling was always off in one way or another. They always felt like the dudes dick were at my knees. With PT AI, this almost completely negates that issue. Can't wait for it to improve even further and SLR to build their cloud function.
I disagree about the green rooms, though. I like the green rooms because I can download the scene and view it locally with PT at a much higher bit rate.
