Because when done in a team where people want to work together and do not have incentives discouraging that it is a really good tool for spreading knowledge and improving maintainability. So far I have only once worked at a place where the review culture was bad and that was due to issues much bigger than the code reviews (specifically a culture where a different team wrote code for another team to maintain, encouraging shoveling shit code over the fence).
