Why do you care?
These events aren't about the TV ratings, they're about creating a special event in the city in which they go. When the All Star Game came to Raleigh 10 years ago, the game itself was stupid boring, but the event itself was the week long festival the city and league put on downtown that attracted people from around the state, country, and continent. There were people in my circle of friends who didn't follow hockey, but actually got hyped for the event. It was genuine fun for the region.
And we are scheduled to have the next Stadium Series game. We are expecting that to be an excellent event as well, and people I know who don't follow hockey are already hitting me up (as a season ticket member) for tickets. Just because you personally don't see the hype or see the fun in it anymore doesn't mean that it doesn't exist.
Always amuses me when I see how frustrated some people get when others are allowed to have a little fun.
