From a show design standpoint, one thing that has bothered me is the team either not taking into account or not really caring about how light and water do very different things once they are off a vertical axis. So, in this screenshot of the Mulan section, you have arcing jets of water (the blue) that are barely illuminated because the lighting (the yellow) is going in a different direction:
You can really see how silly this looks on the arm behind, where only the first few feet of water is visible before it all just disappears because light doesn't bend like water does.
And so you end up with a section like this where a lot of fountains are on, yet you barely see them:
To give another example, here's a close up from one of the video's split screens. In this shot, the fountains on top of the tacos are on but not yet illuminated; we only see them because of the residual glow of the fireworks:
And here's a few frames later with the fountain lights now on. I'm not exactly wowed by the difference:
Maybe this is the look the team were going for. Will everything look better in person with the naked eye? Hopefully. But I'm worried it's just going to look like a mess of bright spotlights and dim fountains going in random directions, because that's kinda how it looks in the videos and pictures.
