Well I agree when a film has an aspect ratio of 2.35:1 widescreen and you take a pan and scan of that to fit into IMAX's aspect ratio: 1.44:1I wonder when this IMAX fad will go away. It gives me headaches, it's unwatchable in the front row, and it adds nothing to the story.
it is like taking any widescreen movie and panning and scanning it to fit it into traditional analog TVs for a broadcast 20 years ago. You are losing 30% of the image as well as the grain is increased.
From what I read in a magazine it was only Transformers 2 that had 8k resolution renders for some scenes shot on 70mm film where it looked great.
