Personally, I think this is a dumb complaint. Many games today do the same, mixing real-time cut-scenes with FMV. Some don't mix shit, like the Uncharteds. Others do mix, like GOW3, saving FMV for the more crazy scenes. With blu-ray there's no huge loss in video quality, sometimes almost none(like in GOW3). People shouldn't be surprised, really. I guess 360-only owners have something to worry about, though.
Where's the joke? I could barely see the difference between real-time cut-scenes and FMV in the demo. Actually I still don't see the difference. Game has excellent video quality.
