That's not actually an answer to the question: What is the benefit of expecting something other than what is offered? The question is a bit introspective, and forces those engaging in that kind of habitual behavior to view what they do with a critical eye, something that perhaps requires more maturity than some are willing to muster.
Yes, we do, but what makes anyone think that Disney hasn't already hit on the perfect mix for the guests that they're targeting?
I made the point a couple of weeks ago about how many guests are very happily spending most of their days walking around the World Showcase Lagoon eating food and drinking wine and taking in some live performances, walking through shops, etc. I made the point a couple of weeks ago that my family spends upward of 45 minutes in The Oasis and Discovery Island Trails at Animal Kingdom, while others are sprinting to FoP. Let's also mention the hour-long queues for meeting costumed characters. And so on.
Some are analyzing Disney as if they view those activities with derision - they seem incapable of appreciating what these other guests appreciate.
Who's right and who's wrong? Neither. However, Disney is devoting a good amount of its attention to the former (and Universal, perhaps, devoting more of its attention to the latter). In that context, and in the black-and-white way that some look at things, I suppose that the thrill ride commands lose - but the reality is that they only lose if they try to fit themselves, as square pegs, into the round holes that Disney furnishes. They whine and cry about how Disney fails, but it isn't Disney that fails but rather they themselves who fail - fail to aim themselves at a venue that is targeted at them, instead insisting that a venue targeted at others be changed to fit their own personal proclivities. And they do it again and again and again, the definition of insanity.
