Some of the decisions are at least debatable in recent weeks, but there are some that IMO (and most others) were clear and obvious errors by the on-field referee. The biggest problem with VAR as a thing, that people have eluded to, is that they seem absolutely unwilling to tell the referee that he was wrong. I think if you asked 100 people, 99 would say that the foul on David Silva against Bournemouth was a penalty, thus it is clear and obvious.
We are too protective of on-field referees in this country. Surely they aren't this proud collective who want to be all powerful and all knowing? If I was a referee I would like to be assisted by my assistants when I clearly made a mistake. VAR is not doing this, so it's kind of idiotic to even use it in the first place... I am all for VAR, but you simply have to change decisions like the Silva one yesterday. IMO it wasn't even a debatable decision but the VAR is looking for any and every possible avenue to agree with what the referee said because they're scared of making the referee look incompetent on live TV.
I don't want to make it out like we were fecked over so I'd rather use examples from other games, but I think there were two challenges on United players against Palace where the obvious decision was red card. A clear goal scoring opportunity was denied. It was outside the box so if this double jeopardy rule is still in place it wouldn't come into play anyway. They were red cards, but only free kicks. Even the second one, most people are saying penalty, but the foul began outside the box IMO. Both decisions should have been free kick and red card, not penalty and yellow card.
