Looks like Disney did a preview show for the "Social Media Moms":
As someone who actually likes World of Color, this looks incredibly boring. It's like they took World of Color, made it slower, and took out all the energy, excitement, and spectacle (except for the last minute or so). Yes, the floats themselves are somewhat technologically impressive, but they get lost in the scale of the lagoon. It's hard to believe that this came from the same entertainment group that did Fantasmic and Illuminations (or, for that matter, Disney Dreams! and Ignite the Dream in Paris and Shanghai).
No one goes to Illuminations just for the Globe segment.
It's only a sneak peak, so I suppose that it could be tweaked before the official opening, but I doubt they can do anything in the next week that they wouldn't have done in the last 10 months since the originally scheduled opening.
