I'm bugged by the inconsistency of hand ball calls.
Barcelona was benefited by 2 hand balls called in their favor that earned a double yellow/red card to a player of the other team.
Earlier that day I watched the Chelsea FA cup game and the same type of hand ball was not even called.
I know it is based on the ref's criteria but the differences in criteria can drive you crazy.
I say that if the ball hits your hand no matter how - it's a handball.
And if its blatant in its voluntary intent - then you yellow card them. Here we again enter the ref's criteria area but I prefer this scenario.
