Uh oh...................here come the strip joint/porn arguments again
Not from me.

I know some take it there, but I really do mean it more generically.
True. But it doesn't automatically mean it SHOULDN'T be there either.
Yes, but I didn't use it as a reason it shouldn't. You (and you're certainly not the first to do this) used it as a reason it should be there. Its more of a "lowest common denominator" of anything on which Disney spends $100 million+. Sort of like safety... its something that must be there, but what is appropriate/advantagous to Disney is a small subset of anything that is safe.
There are other M:S ads that show people being amazed or having fun ... the whole "Dad? Are we still in the building?" series.
I've seen the "scared adults" ad at least 15 times, but never any others. Its possible the local or regional audience is getting a balance, but it doesn't look like the national audience is.
I just think it's too fast-spreading of a story for Disney to have released it because they were drawing attention to a serious problem.
It may very well be that because of the national ad campaign, its become a national story. Or it could be that a lot of people really do think its significant that Disney has the first ride that offers bags. Let's face it, if it wasn't fast spreading, would you be saying its not that big a deal because nobody was reporting it?
As I said ... lots of people get sick on the teacups, but you never see THAT in the news.
That's the problem... Everybody knows the teacups can make you sick. So how bad is M:S if it offers bags and the Tea Cups don't? The perception is going to be that it is much more likely to make you ill, or that it makes people ill who don't otherwise have issues.
Then, poof! You just upped your demographic.
We've been round this topic before, and I know Disney has all but stated this is what they are trying to do. But, it doesn't address what the impact is on the other segments, which are larger, and as AV said, have more disposable income. There's the potential for negative impact to these segments, as well as potential opportunity cost.
If M:S is excluding even some thrill seekers just by the nature of the ride, those potential negative become even more of an issue.
