Not directed at me, but I thought I should respond. Yes, sound/spiels have detail. The narrator's voice quality and vocal inflection are details. The tone of the script and what it references are details. The pace and rhythm of the spiel are details. All work together to affect how the listener experiences the spiel. Talk to any artist who uses their voice as a medium, and you'll be told thoroughly that, yes, sound has detail.
The new narration feels like not much effort was put into it. Some generic ride descriptions were worked up, character voices (not done by the "official" voices mind you, except maybe Mickey, but that's in question) thrown in. There's no theme to it at all. If it really represents the new direction of Tomorrowland, I would say that the new them is a generic, semi-futuristic, kinda sci-fi land that is really just a collection of rides that hardly relate to one another. No sense of place, no story elements, no immersion to speak of. To me, the tone of the spiel translates to: We cant be bothered to even go through the motions anymore, because we gave up long ago.
That kind of Disney, only charactes and franchises, all the time, with no room for anything new or unique, just the same stories over and over again, done a hundred ways to Tuesday, is not a Disney I want to give any of my money to. I'm not the only one who feels this way, and it's not just "purists" or "whiners" (whatever those are) that feel this way. I have friends that like disney films well enough, but aren't fans that would end up on forums, that don't have an interest in spending a bunch on a trip to the parks because, to paraphrase: "It's just the same thing over and over." My father, also not a super fan, preferred TDS over every other park because "It's not just a bunch of character crap."
