So having seen the DIS video of this one, hrrrrrrmmmm...
As others have said, no narrative to tie everything together hinders this show. It's literally a clipshow in the most basic form possible, with no original piece to open and close the show to bring it all together. An for something that's supposed to be about living in unity and harmony, it just doesn't come off that way. Heck, the show is more chaotic and disjointed than anything else at points. An as
@Joe pointed out, there's no harmonizing, that's something that's served on a silver platter on how you can really hammer home the concept and they don't use it.
This show feels like it has a Rivers of Light problem - not enough action. As a show, the last 6 minutes of this show are pretty good, but like RoL with the Lotus float, it's just a good way to end a boring show. My read is they added these screens so you are distracted enough that you don't notice that they massively cut down on pyro throughout almost the entire show.
You're not the only one who feels this show has a Rivers of Light problem, but for me the RoL problem is Harmonius shows it's hand way too early and has nowhere to go from there. After the opening segment, my reaction was "Uh-Ohhhhhh" since I could tell this is how the entire show was gonna' be. It wasn't gonna' throw in any new tricks since it already had the screens, fountains and moving arms going bombastic. (The only surprise to be had was the pyro off the arms way later in the show.)
When you show your hand too early, the show has to truly rely on it's segments and unfortunately most of them weren't that strong for me. Coming back to a earlier comment, the show feels chaotic. You're never really given time to enjoy a piece because it feels like they're changing songs and languages on the fly. I would've preferred if they played a song in it's native language and let it shine. Since a segment I did enjoy early on was the Mulan segment, since that one mainly focused on Reflection and that was seriously beautiful when it did. I wish a lot of the other segments were more like that.
But then we have segments like the France segment which jumped from BatB's prologue to Hellfire to Out There in a matter of second and that just irked me. Felt like a indecisive person at the controls of a radio.
For me, the show didn't pick up until the Coco and PatF segments which I really enjoyed, both of those are easily the strongest segments of the show as it feels like everything is working together the way it should without rapidly jumping from one thing to another. But as mentioned before, when those segments don't kick in till the 14 minute mark on a 20 minute show, that's a BIG problem.
The segments from Mulan, Coco and PatF show there's nice potential for this show, but as it stands those three segments can't save a show which needs a a good amount of editing, a clear focus and...harmony.
