Or it might be better. Once code reviews are happening people tend to start realizing that people are reading their code and it is raised to a higher standard.

Or it might be better. Once code reviews are happening people tend to start realizing that people are reading their code and it is raised to a higher standard. There's also the added benefit that reviewing your code can teach them about better programming practices, and also that reviewing their code with them and asking questions about their thought patterns can make them better developers. It's my opinion that if the code is awful then code reviews become especially helpful and important to bringing everyone up.
