Upvoted because these are all great points that I agree with but code review is still worth the trouble in many situations. On my team it helps us keep a consistent style and forces more people on the team to stay up to date with changes. Code quality is improved because of our review process. Pair programming would accomplish some of that, but not all team members would have a voice. Further, reviews are asynchronous. Sure, reviews are a time sink. No one likes them. We are still better off having done them.
