I think this kind of hits on why I am so curious about the alternatives suggested by critics of Connections as being too much like a modern cafeteria, contemporary corporate architecture, etc. The example of the Atlantic Restaurant just suggests more "stuff" equals more theming/more Disney, even if that busy kind of design isn't really appropriate for the original Epcot aesthetic that they have at least attempted to update.
I don't think you are claiming that aesthetic would work here, though, so that still leaves the question of what would. I have yet to see anyone specify an alternative style for those interiors without using vague concepts about being more engaging, optimistic, forward-looking, or just more Disney.
Well, this is the one alternative people suggest! That, to me at least, seems like nostalgia talking. I can't imagine what people would have said if this really re-opened looking like a freshened up Tomorrowland Terrace or Cosmic Rays.
