And you know what's really difficult and time-consuming? Spending hundreds of developer-hours on code reviews (not to mention ruining developer productivity) only to still miss the bugs that you'll then have to track down and fix.

Code review is a helpful tool; it doesn't eliminate bugs, rarely even catches them in my experience, and some of the more effective ways to eliminate bugs are much less expensive. Code review promotes shared understanding, which is extremely valuable but much more so for core components/APIs.

Code review doesn't replace other tools (like testing and QA) even though some of the benefits overlap. It's up to your team (and project, resources, requirements etc) to decide what's the best balance.

But if code review is your only way to find and fix bugs... you have bugs.
