Yeah, I see more projects with bad code review culture than good. There are many things that managers can do about it.
* Assign enough time for code reviews - otherwise developers will just care about their own code submissions and let reviews rot.
* Establish productive code review rules. E.g. always go from big picture to details, otherwise you'll waste time on details that you end up throwing away.
* Make reviewers co-responsible for the quality of code reviewed, otherwise instant acceptance for everything becomes attractive.
