I thought they were all legit penalty material - granted, none of that would've been called in past years.
The most annoying call was Bouillon for semi-accidentally shooting the puck in the crowd. That cost us 2 goals! But the rules are pretty clear and the NHL has warned the refs that they wanted everything to be called. Players know it too - I can't believe many of them still cross-check from behind, check in the face, hold sticks, etc.
I hate players who do that crap much more than the refs who call them for it.
