I think VAR has been a lot better this season, they just need to keep refining the rules and parameters to suit it. You're never going to completely get rid of inconsistency, but as long as you're not getting decisions that can be justified in isolation it's already a big improvement. They do need to work on imroving consistency in enforcement though, feels like some decisions get checked thoroughly while others are dismissed (incorrectly) at first glance. Case in point, the Laca goal against Leicester.
A lot of the complaints about it are just old farts being old farts. These pundits have been whinging non stop about late offside flags as if it was better when the flags went up quickly and goals/goal scoring opportunities were denied. It's infinitely better this year now that they've aligned with Europe. Then they complain that a clear foul 'is not a clear and obvious error' so the referee shouldn't have checked. The team that deserved a pen is getting a pen, what the hell are you complaining about?
Referees and PGMOL or whatever they call themselves are a joke, and going back to a system that gives them more power and less accountability is not the way forward.
