I think the most frustrating one is that the chopping the arms free kick is being over-policed - players who do make the spoil and then contact the arms or even just the hands in the process. I think commentators mentioned that a couple of times, and since there's no safety issues surrounding that, I'd wager umpires will relax their interpretation on that.

Otherwise, I didn't have a particular problem with the Carlton Essendon game. I thought they generally let things go that would have been paid in the previous couple of weeks. There were a few perplexing decisions - tunneling against Eddie Betts, for example - which looked wrong with the benefit of replay, but the Simpson holding the ball was the only obvious real-time howler for me.
