What the human eye misses and notices in a film varies from person to person, for the image to be a successful illusion of a fictional reality the composer of the image shouldn't second guess what the viewer will not see (unless it's a deliberate artistic decision which in this case it's not).

The tracing in of the missed laser trails in ANH:R adds to the verisimilitude of those sequences (even if it's a near subliminal addition).

I'm not talking about anything ANH:R related. Im talking about people not understanding that when a massive piece of machinery falls to the ground,AT-AT, that it's going to be broken up without having to show CG cracks and armor plating bouncing off the snow like roger rabbit.

Why don't we go the extra step and have Ric Olie pop his head up in the scene to explain it to us in case we didn't understand physics? I understood it when I was 9.
