This is a good one. I've seen (and probably made...) some refactor PRs where someone takes an old system and breaks it up into new conceptual chunks. Code reviewer comes in and they find the new code makes even less sense than the previous code. Of course it so happens that the reviewer already knew the old code, and so it's only natural that new code is less legible to them.
