I saw this guy editing B89 in 4K, and he came back to show off his editing skills for BR.

No BS, I've never once noticed any of these little quirks and mistakes before. It goes to show the difference between a general movie goer/watcher compared to an editor with Eagle Eye vision. Still, some of these edits such as the wobbly sewer bars and the fire breather are simply "blink-once-and-you'll-miss-it" moments. They don't break the movie.
I've always noticed the wobbly steel bars and wobbly background. But for me, it was part of the movie's charm. Ditto most of the rest of that stuff. Good on him for having the technical aptitude to make those changes. But they don't rly bother me.
The only worthy change was adding the eye make-up to the mask ripping scene. I've noticed that detail since I was three years old and this is a perfect example of utilizing technology to correct mistakes like that. It has been often explained that the eye-make up was to make the mask more comfortable for the actor to wear and improve vision. It was lit in a careful manner to not draw attention to it, which wasn't followed when Schumacher was director. I'm not a fan of how it's going to appear in The Batman.
Changes like the firebreather are more obvious and distracting than just seeing those few frames of him on fire before the flames hit him.
