I can obviously only speak for myself, but it's a matter of attention for me. The transitions and sight lines used to be an important part of Disney Parks design. (Heck, it was even part of my Traditions training way back when.). And they passed on a number of projects and project designs because of that. With that, there is also a point at which you can only do so much. Disneyland was masterful at doing this through most of it's time as did original Epcot Center, I would argue. But both had views where it wasn't practical like the skyway and monorails.
But, today, it feels like they just don't care much at all. And, all too often, they are designing things as if they are only viewed from one angle. The "full view" or wide and close up shots have really been lost, presumably because people don't care. Though I would argue, as has been proven with much design especially in hospitality, people often don't know why they perceive quality and attention to detail consciously but they still do.
As a non Disney example, several of the new things feel like that house with the immaculate facade - which you then see is just siding and basic windows on the other three sides. Fine if it's up a hill. But they are now doing that on a corner lot where seeing the side view is guaranteed.
And to your examples, I actually agree with both Alice and Skyliner. They planted trees and put in space to transition from TL to FL, ala the original design. And seeing the peaks of the countries (most of which are finished in all angles, at least at the top) is part of the fun. Where I have an issue is the flat facades of Remy with the very clear show building and supports visible both on the Skyliner and within Epcot. Especially since that was placed where it was for Skyliner purposes. That's where it feels cheap and poor show. (And for SW, my assumption was if you see the unthemed hotel building driving up as the original poster mentioned with no attempt to have it blend in or hide in plain sight.)
Hopefully that gives some better context!
