I just wanted to see other people's opinions on this. Especially Ian's. It was first brought in to make sure there were no calls that were CLEARLY wrong, but most managers have turned it into something to scrutinize calls that could have gone either way, and it's wasting a lot of time in games.

If you're going to let the team's take their time, walk slowly, look back for confirmation before challenging, why make them challenge at all? Why not automatically overturn calls? I still have not got an explanation why they can't employ 1 extra announcer per game as someone overseeing the event from the booth.
