Some people just cannot (or refuse to) recognise all the noise you can see around old/cheap/low quality effects. I often watched those silly Japanese horror varieties where they would show you a grainy video of some dark place, and then maybe a grainy shot of someone crawling out of something. But you know it's two separate things spliced together because the grains are of a different size, or when one area is gray-scale while another is simply decolourised to match. My friends could never tell the difference.

It's easier to suspend your disbelief when you can't see the little squares around the TIE Fighter as it attacks the Millennium Falcon.

Even modern CG is garbage and suffers from the uncanny valley effect.

I don't enjoy Marvel films but even if I did they're unwatchable because of the awful CG.
