VAR is far from perfect as a system, but shouldn't everyone's annoyance be aimed at the people using it? Decisions in football have always been very subjective and therefore different people can have wildly differing opinions on the exact same matter.
That's to be expected from fans, and isn't a big deal since we don't affect the outcome of any given game. Refs, on the other hand, need to be consistent in their application/interpretation, which should hold up under close scrutiny.
What VAR has done is highlight those inconsistencies in their decision making, but instead of most of us realizing that, we seem to jump to the conclusion that the system is rubbish and must be scrapped, since it's application varies from one official to another.
Do I wish that VAR worked better? Absolutely. But let's place the blame squarely where it belongs; with the people using the tool that's been availed to assist them, in a very subjective and inconsistent manner.
