I was open minded about it increasing the percentage of correct decisions when they first said they were bringing it. So I suppose that put me more in the 'for' camp than the 'against' camp but since seeing it in action I'm not a big fan so far. It has bordered on the farcical at times, particularly the Liverpool v Albion cup tie. I will reserve final judgement whilst everybody gets used to it more unless or until it adversely effects The Villa or my football bets.
