A few comments on this topic:
By far most importantly, the games are atrocious due to the refereeing. It's extremely difficult for people to get excited over these absolutely horrid games. Everyone in the crowd talks the entire game about essentially nothing but the officiating and what a complete and utter joke it is. Don't even try to tell me that this is no different than any other tournament, because to date this is the WORST reffed tournament I have ever seen, and indeed, the worst reffed hockey of any kind I've ever seen.
Secondly, I thought the Finland game was quite loud and had a good atmosphere, which has been the only real game so far. I expect the Canada USA game to have a great atmosphere providing the reffing isn't as brutal as in the last few games.
Lastly, I challenge anyone to find me a tournament where Switzerland vs. Norway has attracted over 11,900 fans. That's not sold tickets, that's turnstile entry (they count you when they scan your ticket). The non Canadian games have been extremely well attended, and the support of the tournament overall - not just the Canadian team - has far exceeded my expectations, and any other tournament in the past. Switzerland Norway has been the lowest attended game so far, and still drew 3/4 capacity at about 12000, and the other games have been for the most part nearly full so far.
Noise level is not the end all be all of crowds anyway. It's an intelligent crowd, just not very noisy yet because it's hard to be interested in the garbage being passed off as hockey so far. The only thing that bugs me about the crowd here is the clear anti American feeling. If I thought it were purely a hockey rivalry thing, it would be fine, but pent up frustration due to American politics, foreign policy, etc, as well as a general undercurrent of blind anti Americanism that seems to be ingrained in Canadian culture manifesting itself as booing 18 and 19 year old kids is dumb. But let's not get into that again.
