We used to have these shit developers and I accepted a lot of bad code back then – if it actually worked – because otherwise “code review” is full-on training, which is an entire other job from the one I was hired to do.
The client ditched that contracting firm, and the devs I work with now are worth putting in time on code review with – but damn, we got hella shit code in our codebase to deal with now. Some of it got tossed, some of it … we live with.
