I thought that in general it worked really well in the World Cup, and I was firmly in the "this is going to ruin the tournament" camp beforehand.On the whole it wasn't quite as obtrusive in the World Cup as I anticipated, and yes it will will right SOME wrongs. But you're still just swapping one set of controversies for a bunch of new ones, and introducing a whole raft of new delays and pauses to accommodate it. There are inevitably still going to be some right old f-ups, and the sense of injustice will only be intensified because the officials have had an opportunity to review it and STILL get it 'wrong'. Nobody always agrees on everything.
Its great to sort out obvious errors. Its the myriad of marginal calls where the all the minefields lay ahead.
I'm totally in favour now, despite the fact that there will still be teething problems for years to come.
Partly because I think it's obvious that it DOES mean fewer terrible decisions, but mainly because it will mean that Zaha is FINISHED. [emoji23]
