It's a good idea poorly implemented, and they don't stick to their own guidelines.

VAR should be used only when there is a "clear and obvious" error by the match officials.

3mm offside, is not a clear and obvious error.

Also if the VAR official spends 5 minutes looking at an incident from 20 different camera angles, it is also unlikely to be clear and obvious.

I think they should consider moving to a tennis type model, where each manager has a maximum of, say, 3no. challenges per half if they think the decision was wrong, and if they are right they keep the challenge, if wrong they lose it.
