In a way it is a positive, in favour of VAR.
If VAR was not around, it would have definitely been chalked off.
Just like cricket and other sports, video technology has been brought in to eliminate obvious and clear errors from the officials, they are human it will happen with or without VAR. Even the best officials will make clear and atrocious errors and this is brought in to make the game fairer.
The reason why it has not worked is because:
1: Fans inside and outside of the stadium do not see or hear the process (maybe fans outside will see the replays being shown but there is no obvious this is why we are showing this angle, this is why we are slowing it down, etc.)
2: They try to be too fancy with it, when it is not designed for that. i.e. the offside lines, etc.
3: Part of point 1 but they also, on a lot of occasions, I have seen take away the context of the angle, speed. Take Allan last season, to initially show the on-field ref the still shot of the contact was, at worst, a misjudgment of the technology. The order should be, in real time, slow motion for impact areas and then a still shot if is still a 50/50 call.
4: Obvious bias to certain clubs being even made more obvious by all of the above.
