I saw the LOTR films in the theater, and have watched them repeatedly on DVD.
Saturday night, I saw part of Return of the King on a large flatscreen (probably in excess of 48") and couldn’t help but notice (as did others present) that parts of the image looked especially artificial. The way I would describe it is that it looked like videotape rather than film. Oddly, it seemed to be the live-action parts of the image moreso than the CGI bits.
What causes this? Was some setting on the TV adjusted poorly, or is this an artifact of HDTV compression?
Saw most of I Am Legend afterward, and didn’t notice this effect nearly as much.
