Heck, even the very first official hockey game, using the very first written set of rules for the referee to adhere to, was filled with controversy. Here's what the Kingston Whig-Standard had to say about that very first game in Montreal way back in 1875:
"A disgraceful sight took place at Montreal at the Victoria Skating after a game of hockey. Shins and heads were battered, benches smashed, and the lady spectators fled in confusion."
Sounds to me like the ref had a tough game that night. And it has carried through to every hockey game since.
I accept that refereeing will be imperfect, and I don't even really have a problem with that. Whenever someone cries out about the officiating travesties, I always point out that the hockey gods usually ensure that the bounces even out before all is said and done. Just ask O.J.
