Had a chance to view this for the third time, and this time on ScreenX (we have two of them in the greater LA area).
Regarding ScreenX, I had assumed that there would be three screens and would be viewing this as if it was a Cinerama experience. However, there was in fact one screen. The right and left side are just walls, however there are projectors placed on top of either side, thus completing that 270-degree image. I have to admit, that at first I was wowed when it was first introduced; it certainly did feel like I was surrounded by the movie.
However, that 270 degree image is
not constant. During the slower parts of the movie, the image is only playing in that center screen!
Only when the action starts to pick up, do the walls light up again. And that is basically how it was during the entire movie. I still say the best possible viewing experience is on IMAX.
Despite all of this ScreenX gimmick, I still very much enjoyed the movie and of course, catch things I missed in the first two go rounds, such as Ghidrah saber-rattling his tail when he is awakened, and an image of Behemoth can be seen right there in the very beginning of the opening credits.
Using Leonard Maltin's ratings guide, G:KOTM still garners a solid *** stars, while the ScreenX experience receives **1/2 stars.
