I struggle to fully envisage the gravity box from inside the MK. It will indeed be set back from the park, being hidden from view in the front by the canopy. Itself a bit so-so... A show building hiding itself in plain view a bit. Quite pretty however, to view from underneath is great.
I actually saw and rode Tron in Shanghai. The box is not visible from the park, that I recall, although the setting is completely different. I thought Shanghai TL rather attractive. But a very different aesthetic to MK TL. Incorporating Tron in the MK will be a difficult marriage. Or is that the reverse - incorporating TL aesthetics to Tron...
My foremost gripe is the massive volume looming over and directly next to SM. This diminishes the illusion of great size of SM. Straight lines angling towards one another create an illusion of size and distance, mimicking as they do lines fading off into the horizon.
Also, from the ferry or monorail, from anywhere but the top of the nearest hotels, the MK has got no visible show buildings. This helps to create an illusion of a magic world.
