IMO, it is a missed opportunity. This building could have easily added to and enhanced what catches the focus of the eye. Considering its size and location, if it were given a proper facade it could very well become a part of the already amazing architecture of the park rather than just a big blue box.I'm letting the building's paint scheme do what it is intended to do which is letting the structure fade away in the background to let the other buildings catch the focus of the eye.
When building EPCOT, they were severely over budget, yet they did not make the buildings that house(d) Imagination, WoM, Horizons, or The Land a simple box design painted to match the sky. They spent the money and the buildings became timeless instead of fading away into the background.
