The gargantuan Sorcerer Mickey hat blocking the view of the world-famous movie theater at the end of the park's Hollywood Blvd made as much sense as having a 100-foor-tall fake-looking Glass Slipper sitting in the middle of the Plaza at MK, blocking the view of Cinderella Castle.
Not only was that "hat" completely out of place, it looked more like a blue plastic traffic cone than a silk sorcerer cap.
As far as the "empty space" is concerned, I would be very happy to have a Plaza as the hub of the park, with trees, planters, benches, walkways, with an old Hollywood fair.
