One of the big problems with long-running development projects, especially big ones, are that knowledge around certain areas tend to pile up on certain people, creating "knowledge silos". Unfortunately, this process is also self-perpetuating, as people tend to draw to working with things they know, and avoid what they don't know. Starting a code review process won't even out this landscape completely, but it will give people enough of a boost to dare venture into the code by themselves, hopefully breaking any negative spiral that may have been created. It also helps bring new members of the team into the code base quickly.
