If it's stuff I have have been doing for years and isn't terribly complex I've found its generally quick to skim review. I don't need to read every line I can glance at it, know it's a loop and why, a function call or whatever. If I see something unusual I take that as an opportunity to learn.

I've seen LLMs write some really bad code a few times lately it seems almost worse than what they were doing 6 or 8 months ago. Could be my imagination but it seems that way.
