The good or the bad? Its depends on the side that came something is always against you if you a bettor but just few times it favour you.

I see the no reason when Ref , almost three of four at the line there doing nothing? Only VAR decide what to happen? 

And funny enough most times, when Ref when to check the VAR he still has that power to decide something before coming back outside so why the need for VAR.... Shit
