Unfortunately, I've worked on teams where reviews caused a great deal of tension. I think it's a practice that needs to be closely monitored, depending on the team personalities. I guess some people see it as an opportunity to try and stroke their ego. In some cases, it can poison the well for an entire team while simultaneously forcing productivity to a crawl.
I certainly can imagine this happening. If this happens, I see it as an opportunity for team members to grow personally, to become kinder, to realize other people are people too. I'm sure it can be worked on, if they want to improve.
